Management of urinary tract infection in women: A practical approach for everyday practice Nassib F Abou Heidar, Jad A Degheili, Aline A Yacoubian, Raja B Khauli Urology Annals 2019 11(4):339-346 A common health-care problem worldwide, urinary tract infection (UTI), represents a disease of significant impact on every country's economy, being the most common cause of hospitalization among elderly people and the most common cause of antibiotic prescription in primary care. Diagnosing and managing upper and lower UTI have always been a challenge to physicians, given its high prevalence, risk of recurrence and improper treatment, and the fact of worldwide increase in antibiotic resistance, necessitating implementation of a proper antibiotic stewardship. Urinary infections are twice more likely to occur in females compared to males and its prevalence increases with increasing age. The following is a comprehensive review paper about UTI in females, discussing the various factors leading to a complicated infection. The various etiologies and microbiologies of UTI are also highlighted. In addition to various usual antibiotic regimens for treating UTI, a significant number of nonantimicrobial treatment modalities are highlighted and described in this manuscript, including the novel use of intravesical antibiotics and vaccines for suppression treatment. Finally, a pathway is suggested for the proper diagnosis and treatment that ensures antibiotic stewardship in order to decrease long-term complications.

Prevalence and characterization of urolithiasis in the Western region of Saudi Arabia Anmar M Nassir Urology Annals 2019 11(4):347-352 Objectives: The main objective of this study is to determine the prevalence and risk factors of urolithiasis among the Saudi population in Makkah region. Methods: A cross-sectional survey was conducted on February 2017 in Makkah region (Makkah, Jeddah, and Taif). Data were obtained through direct interviews with participants, using an 18-questions-self-questionnaire, inquiring about demographic data (age, gender, weight, height, location, and occupation), educational level, history of renal stone disease (symptoms, modality of diagnosis, hospital admission, and previous treatment), and risk factors of stone formation such as family history and daily fluid intake. Results: A total of 1506 individuals were interviewed, including 82% from Makkah, 15.7% from Jeddah, and only 2.3% from Taif. The overall percentage of those diagnosed urolithiasis was 6.2%; including 6.6% males and 5.8% females (P = 0.06). Of those with stones, 5% were medically treated, 1.7% were hospitalized, and 1.2% were surgically managed for stones. There was a positive linear correlation between the prevalence of stones and participants' age group (r = 0.87, P = 0.01). More than 80% of participants were highly educated, which did not impact the prevalence of stones formation (P = 0.14). Urolithiasis was reported by 8.9% obese participants, 5.9% overweight, and 5.4% with normal body mass index (r = 0.68, P = 0.03). When stratified by jobs, stone prevalence significantly increased in retired participants (17.2%) than in workers (8.8%), followed by those without work (7.7%) and finally by students (3.3%) (P < 0.001). There was no significant difference between urolithiasis and type of drinking water (P = 0.62). Conclusion: The prevalence of urolithiasis in the Western region of Saudi Arabia has not changed much since the previous report, which was 30 years ago. It seems that the middle-aged population in their third decade of life, those who are overweight and obese people are at a high risk of developing urolithiasis.

The incidence and pattern of renal cell carcinoma recurrence after robotic partial nephrectomy Mohamad W Salkini, Nabhan Idris, Abdul Raof Lamoshi Urology Annals 2019 11(4):353-357 Background: Robotic partial nephrectomy (RPN) is a rapidly growing treatment for small renal mass (SRM). In fact, RPN has shown good functional and oncologic outcome. In this manuscript, we are reporting on the incidence and pattern of recurrence of renal cell carcinoma (RCC) treated with RPN. Patients and Methods: We reviewed prospectively collected data of patients who underwent RPN between September 2009 and March 2018. We selected patients with final pathologic diagnosis of RCC after the resection of their SRM. We described the incidence and pattern of recurrence in the patients who had it. Results: A total of 335 patients with SRM underwent RPN. We found 269 patients to have RCC on the final pathologic evaluation of the SRM. Eight cases of recurrence were found with a recurrence rate of 2.9% after the mean follow-up period of 31 months (range 18–72). The pattern of recurrence presented as follows: two patients (0.7%) had trocar site recurrence (TSR), one patient (0.37%) had locoregional recurrence, and three patients (1.1%) had recurrence of the disease at the resection bed. Two patients (0.7%) developed second primary tumor in the other kidney. No cancer-related mortality occurred during the follow-up period. Conclusion: TSR, locoregional recurrence, tumor bed recurrence, and contralateral tumor development are observed patterns of RCC recurrence after RPN. Recurrence was seen in up to 72 months. RPN provides great cancer control and high cure rate when utilized to treat RCC presenting as SRM.

Outcome of thulium laser enucleation of prostate surgery in high-risk patients with benign prostatic hyperplasia Ketan P Vartak, Kshitij Raghuvanshi Urology Annals 2019 11(4):358-362 Background: Benign prostatic hyperplasia (BPH) is one of the most common diseases in aging men and a significant cause of burden worldwide. Here, we report our experience of Thulium LASER enucleation of the prostate (ThuLEP) in high-risk patients with BPH. Methods: This was a prospective study conducted between July 2011 and June 2016. The study participants were patients with a confirmed diagnosis of BPH, who required surgery, and were clinically eligible for ThuLEP. Results: A total of 109 patients were included in the study. Of the total 109 patients, 82 patients had American Society of Anesthesiologists (ASA) Grade 3 and 27 had ASA Grade 4. The most common comorbidity was ischemic heart diseases (72.5%), followed by hypertension (57.8%) and diabetes mellitus (48.6%). During the procedure, a total of 11 (10.1%) patients had a fall in blood pressure requiring noradrenaline or mephentine and seven (6.4%) patients had early left ventricular failure. Sixteen (14.8%) patients had arrhythmias (benign) and seven (6.4%) patients with arrhythmias required antiarrhythmic drugs. The overall duration of surgery ranged from 55 to 70 min, laser time ranged from 25 to 35 min, hospital stay ranged from 30 to 36 h, and the mean catheter time was around 24 h. Overall, the change in hemoglobin ranged from 0.5 to 0.8 g/dL. Conclusion: Results show that ThuLEP could be a better option in high-risk patients with BPH.

Efficacy of intercostal nerve block with 0.25% bupivacaine in percutaneous nephrolithotomy: A prospective randomized clinical trial Iqbal Singh, Om Kumar Yadav, Sanjay Gupta Urology Annals 2019 11(4):363-368 Introduction and Aim: Several techniques have been used to lower the morbidity of percutaneous nephrostomy (PCN) tube after percutaneous nephrolithotomy (PCNL). The outcomes of intercostal nerve block (ICB) versus peritubal block (PTB) with 0.25% bupivacaine to alleviate post-PCNL pain were compared. Materials and Methods: After obtaining an informed written consent and local institutional ethics clearance, 64 patients undergoing PCNL were computer randomized to receive either an intercostal block/ICB (Group I) or a peritubal block/PTB (Group II) using 0.25% bupivacaine infiltration, after termination of the procedure. They were evaluated for visual analog scale (VAS) score, first analgesic requirement, and the total analgesic demand along with fall in hematocrit, PCN indwelling time, blood transfusion rate, complications, and mean hospital stay in the postoperative period. The protocol was registered with CTRI/2018/03/012717. Results: Patients in both the groups were comparable on the basis of demographic data, preoperative renal function, stone burden, and hematocrit value. The mean VAS score at 6, 12, 24, and 48 h was significantly lower in the Group II versus Group I (P < 0.001). The total mean analgesic requirement was 160.16 and 103.13 mg of diclofenac sodium in Group I and Group II, respectively, which was significantly higher in Group I versus Group II (P < 0.001). The time to first analgesic demand was significantly higher in PT group (8.06 ± 1.99 h vs. 12.97 ± 1.96 h) in Group I/ICNB and Group II/PT, respectively (P < 0.001). Both the groups were comparable in terms of postoperative hematuria, hematocrit fall, nephrostomy site leak, hospital stay, need of blood transfusions, stone-free rate/retreatment rate, postoperative urinary tract infections, and overall complication rate (Modified Clavien–Dindo classification) which were not statistically significant. Conclusion: Post PCNL, PTB was associated with significantly lower post operative pain and discomfort versus ICB as demonstrated by the significantly lower DVAS pain scores, higher mean time to first analgesic demand and lower mean total analgesic demandt with ICB. Bupivacaine was a safe and effective local anesthetic agent for PTB in select patients for facilitating quick relief from the morbid postoperative pain and discomfort following PCNL.

Oral dissolution therapy for renal radiolucent stones, outcome, and factors affecting response: A prospective study Shady Mohammed Salem, Mohammed Farag Sultan, Atef Badawy Urology Annals 2019 11(4):369-373 Background: Urolithiasis is a widespread problem, that affects up to 10% of population. Uric acid stones come second to calcium stones in prevalence (around 10% of urolithiasis). Potassium citrate is currently the treatment of choice for urine alkalization with minimal side effects and high tolerability. Aims and Objectives: This study is trying to present the outcome of oral dissolution therapy (ODT) for treating radiolucent renal stones and evaluating factors affecting its success in a prospective manner. Materials and Methods: Between 2015 and 2018, 147 patients with solitary radiolucent renal stones were offered ODT using potassium sodium hydrogen citrate (K citrate). The study included patients diagnosed by noncontrast computed tomography (NCCT) with stone size of 5–30 mm in the longest dimension and attenuation less than 600 Hounsfield units (HU) . Patient compliance, blood pressure, creatinine level, K level, and tolerance to side effects were followed up at days 3, 7, and 15 and then monthly for 3 months. Follow-up renal ultrasound at 6-week intervals and a final NCCT at the end of treatment. Successful dissolution was defined as complete stone dissolution or residual that measures up to 2 mm in maximum length. Data were collected, tabulated, and analyzed using Stata 12.0 software (Stata Corporation, College Station, TX, USA). Results: One hundred and thirty-nine patients were included in the analyses. The age was 45.1 ± 10.5 years. DJ stent was used in 47 (33.8%) patients. Overall response rate was 64.8%. The stone location within the kidney (pelvic or calyceal) showed no difference between responders and non-responders. Stone longest diameter was smaller in responders ( 17 ± 5.7 mm) versus 19.2 ± 6.1 mm in nonresponders (P value = 0.039). The mean stone attenuation value (HU) was also lower in responders( 347.4 ± 68.5 HU) versus (428.9 ± 84.0 HU) in nonresponders with P < 0.001. DJ insertions seemed to have marginal effect on stone dissolution on univariate analysis but found insignificant in multivariate analysis. Conclusion: ODT is safe and effective in the treatment of radiolucent renal stones. The efficacy was affected by stone density and stone size with more tendencies to failure with bigger stones and denser stones. Double J stent insertion may facilitate dissolution rate. There was no effect of the baseline urinarypH, hyperuricemia, or stone location on the dissolution rate of the stones.

Modification of microsurgical longitudinal intussusception technique of vaso-epididymal anastomosis: A single-center experience Rajendra K Shimpi, Krutik V Raval, Darshan N Patel Urology Annals 2019 11(4):374-379 Purpose: Microsurgical intussusception vasoepididymostomy (VE) is well-established treatment option for obstructive azoospermia due to epididymal obstruction. In this study, we evaluated patency rates and complications of our modified longitudinal intussusception technique of microsurgical VE. We have modified the intussusception technique by taking only adventitia of epididymal tubule. Methods: This was a prospective, single-center (tertiary care center) study conducted from February 2008 to January 2016. Study patients were men aged more than 18 years with infertility due to azoospermia. All participants underwent microscopic VE with our modified intussusception technique. Patency rates, complications, and improvement in semen quality were assessed. Results: A total of 42 patients were included in the study and underwent unilateral VE using longitudinal intussusceptions technique. The mean age of the patients was 30.21 years. Of these 42 patients, 40 patients had congenital obstruction. Average operative time was 130.42 min. A total of 36 (85.7%) patients had motile sperms in the epididymal fluid. Patency at 3 months was observed in 25 (62.5%) patients with an average sperm count of 17.1 million/mL. Only two patients (5%) had hemotoma at the site of surgery. Conclusion: Our modified technique of microsurgical longitudinal intussusception VE using epididymal adventitial stitch showed a reasonable patency rate after surgery.

To study the incidence and preintervention factors associated with acute kidney injury in patients diagnosed with ureteric calculi Sheshang Uday Kamath, Bhushan Patil, Sujata Kiran Patwardhan Urology Annals 2019 11(4):380-384 Aims and Objectives: The study aims to evaluate the incidence and factors associated with acute kidney injury (AKI) among patients presenting with ureteric calculi. We also intend to study the impact of time delay since first symptom to presentation to our hospital among patients with ureteric calculi and its influence on AKI. Material and Method: The study is a prospective observational study and included all symptomatic ureteric calculi patients. AKI was defined as per the KDIGO guidelines. All the patients diagnosed with ureteric calculi were grouped into those having an episode of AKI and those without an episode on AKI. Results: The incidence of AKI in our study was 14.63% (18 patients) among 123 patients of ureteric calculi. Average time delay from time of diagnosis to presentation among patients with AKI was 31.7±6.2 days (mean ± S.D) as compared to 19.5±5.7 (mean ± S.D) days among all cases. Factors which were significantly associated with AKI in patients with ureteric calculi include time delay, diabetes mellitus, bilateral ureteric calculi, stone size greater than 10 mm, solitary functioning kidney and urine culture showing gram negative growth. Fifty percent of the AKI group eventual required nephrectomy of one renal unit. Conclusion: This study will help us streamline our resources predominantly towards those patients who present with factors associated with increased risk of AKI. As the time delay to presentation in patients with AKI with ureteric calculi is significantly higher, it is imperative to counsel patients with stone disease.

Retrospective review of experience with sarcomatoid renal cell carcinoma: Multimodality treatment remains an unmet goal Gowrinath Kondisetty, Pallavi Vijay Borkar, Sandeep Kondisetty, Appu Thomas Urology Annals 2019 11(4):385-388 Background: Sarcomatoid change in Renal cell carcinoma(RCC) is associated with adverse outcomes with median survival of 6 months. Settings and Design: This is a retrospective study of patients diagnosed of sarcomatoid RCC(sRCC) between 2007 and 2013 which were followed up till 2017. Methods and Material: Patients (n=22) were grouped based on whether they received additional chemotherapy following nephrectomy. Two groups were followed up until 2017 and overall survival was record. Overall survival curves were estimated by Kaplan-Meier method and compared using Log Rank (Mantel-Cox) test between two groups. Statistical analysis used: Kaplan-Meier method and Log Rank (Mantel-Cox) test. Results: The patients who had chemotherapy had 13.4 cm of mean tumour size with a mean survival of 20.4 ± 8.3 months. The patients who did not undergo chemotherapy had mean tumour size of 11.7 cm with a mean survival of 21 ± 5.9 months. There was no much statistical difference between the two groups in OS with P value = 0.99. Conclusion: The current adjuvant chemotherapy used in sRCC patients who develop metastasis gives no survival advantage.

Tuberculosis of the prostate gland masquerading prostate cancer; five cases experience at IGIMS Kumar Gaurav Mishra, Ahsan Ahmad, Gaurav Singh, Rajesh Tiwari Urology Annals 2019 11(4):389-392 Objectives: Tuberculosis (TB) of the prostate is a very rare disease. Most urologists are not familiar with it. Here, we present our experience with five cases of this disease and a review of literature. Materials and Methods: This is a retrospective study in a tertiary care center (IGIMS, Patna, Bihar, India) from January 2013 to February 2018. Results: All the patients were in their fourth to sixth decades of life. Lower urinary tract symptom was the most common presentation, predominantly irritative symptoms. A history of pulmonary TB was present in one case. Four out of five cases (80%) had a suspicious prostate on the digital rectal examination (DRE) (hard in consistency). Serum prostate-specific antigen (PSA) level was slightly elevated with a mean of 13.24 ng/ml. Urine analysis revealed sterile pyuria in all patients, and the urine culture was negative. The urine for acid-fast bacilli was positive in one case (20%). Mycobacterium tuberculosis culture test was positive in two cases (40%). The transrectal ultrasonogram showed hypoechoic areas with irregular outlines in three cases (60%) and calcification in two cases (40%). Histopathological examination showed chronic granulomatous prostatitis with few Langhans-type giant cells in four cases (80%). All patients were scheduled to receive 6 months of chemotherapy with isoniazid, rifampicin, and ethambutol or pyrazinamide. Conclusion: TB of the prostate may present like cancer prostate with raised serum PSA and suspicious prostate on DRE; hence, a high index of suspicion with a wide range of investigations may be required to achieve a complete diagnosis of prostatic TB.
