Predictors of forniceal rupture in patients with obstructing ureteral calculi: Analysis of multicenter data.

Background: Renal forniceal rupture (FR) is a unique complication of obstructive uropathy. This study aimed to identify the predictors of FR among patients presenting with renal colic due to obstructing ureteral calculi. Materials and Methods: After obtaining ethics approval, electronic records of patients from three National Guard hospitals in Saudi Arabia were reviewed between 2016 and 2020 to identify patients who presented with renal colic and were diagnosed with FR due to obstructive ureteric stones (FR group). An equivalent number of consecutive patients presenting with renal colic due to obstructing ureteric stones without FR was selected as a control group (non-FR group). Patients were grouped according to age group (<30, 30-40, 41-50, and >50 years), body mass index (BMI) class, gender, comorbidities, grade of hydronephrosis, location of the stone in the ureter, size of the stone (<3 mm, 3-7 mm, and >7 mm), and stone former status. Baseline patients' and stone characteristics were compared, and a regression analysis was performed to identify predictors of FR. Results: A total of 50 patients with FR were identified, and a control group of 50 patients without FR were selected. The baseline patients' and stone demographic characteristics in terms of age (P = 0.42), gender (P = 0.275), BMI (P = 0.672), comorbidity, grade of hydronephrosis (P = 0.201), and stone location (P = 0.639) were comparable between the FR group and the non-FR group. However, the stone size was statistically significant between both groups (P = 0.014). On multivariable analysis, it was found that the stone size was associated with a significantly higher increase in the incidence of FR (odds ratio [OR]: 6.5 [1.235-34.434]; P = 0.027). Furthermore, the age group between 30 and 40 years was potentially at a lower risk for FR (OR: 0.262 [0.069-0.999]; P = 0.049). Conclusion: This multicenter study showed that the stone size 3-7 mm had a six-fold increase in the chance of FR, and the age group between 30 and 40 years is potentially at a lower risk for FR.

AUA-recommended Antibiotic Prophylaxis for Primary Penile Implantation Results in a Higher, Not Lower, Risk for Postoperative Infection: A Multicenter Analysis.

PURPOSE: Our aim was to determine if the AUA-recommended prophylaxis (vancomycin + gentamicin alone) for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard regimens. MATERIALS AND METHODS: We performed a multicenter, retrospective study of patients undergoing primary inflatable penile prosthesis surgery. Patients were divided into those receiving vancomycin + gentamicin alone and those receiving any other regimen. A Cox proportional-hazards model was constructed adjusted for major predictors. A subgroup analysis to identify the appropriate dosage of gentamicin was also performed. RESULTS: A total of 4,161 patients underwent primary inflatable penile prosthesis placement (2,411 received vancomycin + gentamicin alone and 1,750 received other regimens). The infection rate was similar between groups, 1% vs 1.2% for standard vs nonstandard prophylaxis. In the multivariable analysis, vancomycin + gentamicin (HR: 2.7, 95% CI: 1.4 to 5.4, P = .004) and diabetes (HR: 1.9, 95% CI: 1.03 to 3.4, P = .04) were significantly associated with a higher risk of infection. Antifungals (HR: 0.08, 95% CI: 0.03 to 0.19, P < .001) were associated with lower risk of infection. There was no statistically significant difference in infection rate between weight-based gentamicin compared to 80 mg gentamicin (HR: 2.9, 95% CI: 0.83 to 10, P = .1). CONCLUSIONS: Vancomycin + gentamicin alone for antibiotic prophylaxis for primary inflatable penile prosthesis surgery is associated with a higher infection risk than nonstandard antibiotic regimens while antifungal use is associated with lower infection risk. A critical review of the recommended antimicrobial prophylactic regimens is needed. Prospective research is needed to further elucidate best practices in inflatable penile prosthesis antimicrobial prophylaxis.

Empirical therapy for male factor infertility: Survey of the current practice.

BACKGROUND: Empirical therapy is sometimes used by urologists who desire to improve the outcomes for infertility patients. However, the literature on empirical therapies is scarce. Therefore, we aimed to assess the clinical practice of urologists regarding the use of empirical therapy in the treatment of infertility patients. METHODOLOGY: An online survey using Google Forms was used to collect data during the Saudi Urological Association Annual Meeting, February 2019. Additional data were gathered electronically in March and April 2019 and sent to respondents. The study was closed in May 2019. No incentives were provided to the respondents. RESULTS: A total of 96 (80%) urologists participated in the survey, of whom 69.8% were consultants, and 20.8% were andrology-trained urologists. Empirical therapy was used by 86.5% of urologists for patients with idiopathic oligoasthenoteratozoospermia. The most commonly used empirical therapies were zinc, L-canitine, clomiphene citrate, and L-arginine. The main factors that influenced the selection of empirical therapy were follicle-stimulating hormone, total testosterone, and luteinizing hormone levels. CONCLUSION: Empirical therapy was used by more than three-quarters of the participants for idiopathic male infertility. There were no clear guidelines for the ideal therapy to be considered for individual patients while treating empirically. Our concern is that urologists use a wide variety of medications without significant data to support these medications.

Current surgical procedures for benign prostatic hyperplasia and impression of new surgical modalities.

BACKGROUND: Surgery is considered the most effective treatment for Benign prostatic hyperplasia (BPH) and Transurethral resection of prostat (TURP) is considered the gold standard. The goal of this study is to assess the surgical interventions used in Saudi Arabia, the difference in surgical procedures done depending on age and years of experience and the participant's impression on the new modalities in the management of BPH. METHODOLOGY: An online survey using Google Forms was sent to the participants. The data were collected during Saudi Urological Association Annual Meeting February 2019. Additional data were gathered 2 months later. The study was closed in May 2019. No incentives were provided to participants. RESULTS: A total of 65 (54.1% response rate) urologist participated in the survey, of whom 41.5% of respondents were aged <40 years, while 40% of them aged between 40 and 60 years. Forty-seven (72.3%) out of 65 were consultants. The essential investigations used by most participants prior to surgical interventions are prostate specific antigen, urine culture, urinalysis, and abdominal ultrasound. The most used surgical interventions are unipolar transurethral resection (TURP), Bipolar TURP, and open prostatectomy. About 50% of respondents preferred open prostatectomy for prostate size above 100 g. In general, 40%-50% of participants believe that urethral lift, Rezum, Aquablation, prostate artery embolization, and robotic simple prostatectomy are useful options. CONCLUSION: TURP continues to be the main intervention for prostate sizes <100 g. Open prostatectomy is widely used intervention for prostate sizes more than 100 g. New modalities gained little acceptance among urologist practicing in Saudi Arabia. Hands on workshops may help in educating urologists and introduce these new modalities for the future use.

Adult urethral stricture: Practice and expertise of urologists in Saudi Arabia.

OBJECTIVE: The aim of this study is to determine the methods used to evaluate and manage urethral strictures by urologists practicing in Saudi Arabia. MATERIALS AND METHODS: This is a cross-sectional study based on a validated questionnaire directed to all urologists and senior residents practicing in Saudi Arabia. Categorical data reported as frequencies and percentages. A Chi-square test was used for inferential analysis. P < 0.05 was considered statistically significant. RESULTS: We received 112 responses, of which 78% were from board-certified urologists. The majority were working in government hospitals. The rate of endoscopic procedures performed exceeded open urethroplasty. Direct Vision Internal Urethrotomy was the most common procedure performed as stated by 85% of the responses. Uroflowmetry with postvoid residual was the most common investigation requested to assess strictures before and after the operation usually in adjunction with retrograde urethrogram and or cystoscopy. Most of the urologists believed in a step-wise approach in the management of strictures and that urethroplasty is indicated only after repeated trials of endoscopic management. CONCLUSION: Our results revealed a preference, and perhaps misuse, of endoscopy which might raise a concern regarding patients' prognosis with repeated endoscopic management. Most of the urologists seem to be reluctant to proceed to a definitive treatment on the time of diagnosis either due to a lack of experience or knowledge. The results showed no difference between practice in government and private hospitals.

The prevalence of urinary tract infection, or urosepsis following transrectal ultrasound-guided prostate biopsy in a subset of the Saudi population and patterns of susceptibility to flouroquinolones.

OBJECTIVES: To study the prevalence of urinary tract infections (UTI), or sepsis secondary to trans-rectal ultrasound-guided (TRUS) biopsy of the prostate, the pathogens involved, and patterns of antibiotic resistance in a cohort of patients. METHODS: This is a descriptive study of a consecutive cohort of patients who underwent elective TRUS biopsy at King Abdulaziz Medical City, Riyadh, Saudi Arabia between January 2012 and December 2014. All patients who underwent the TRUS guided prostate biopsy were prescribed the standard prophylactic antibiotics. Variables included were patients' demographics, type of antibiotic prophylaxis, results of biopsy, the rate of UTI, and urosepsis with the type of pathogen(s) involved and its/their antimicrobial sensitivity.  RESULTS: Simple descriptive statistics were used in a total of 139 consecutive patients. Urosepsis requiring hospital admission was encountered in 7 (5%) patients and uncomplicated UTI was observed in 4 (2.8%). The most common pathogens were Escherichia coli (90.1%) and Klebsiella pneumoniae (9.1%). Resistance to the routinely used prophylaxis (ciprofloxacin) was observed in 10 of these patients (90.9%). CONCLUSION: This showed an increase in the rate of infectious complications after TRUS prostate biopsy. Ciprofloxacin resistance was found in 90.9% of patients with no sepsis.
