    Abstract: Predicting successful sperm retrieval is essential in counseling infertile men with Azoospermia. Objectives To assess the predictors of successful sperm extraction in men with nonobstructive Azoospermia. Patients and Methods A retrospective study included all patients with nonobstructive Azoospermia from January 2018 to May 2019. Subdivided into two groups, group I (negative sperm retrieval) and group II (positive sperm retrieval). Results A total of 108 patients with a mean age of 36.8 ± 10 years were included. The rate of successful sperm retrieval was 47.2%. Group I included 57 patients (52.8%) with a mean age of 33.98 ± 6.18, and group II included 51 patients (47.2%) with a mean age of 40.04 ± 12.22 ( p  = 0.008). Follicular stimulating hormone (FSH) levels were significantly higher in group I (18.55 ± 13 vs. 7.97 ± 7.11; p   〈  0.004). Similarly, in group I, luteinizing hormone was significantly higher (11.4 ± 7.45 vs. 5.9 ± 4.4; p   〈  0.001). Age and FSH were the independent predictors of successful micro‐TESE. Additionally, successful pregnancies were 13.7% of patients, 28.6% of which gave rise to living birth. Conclusion Patients' age and serum FSH are independent predictors of successful sperm retrieval for infertile men with nonobstructive Azoospermia; young patients with high FSH levels could have little chance of sperm retrieval.

    Abstract: Purpose: To compare the rate of post-flexible ureteroscopy urinary tract infection (UTI) in patients subjected to the standard antibiotic prophylaxis alone versus enhanced prophylactic measures. Methods: A prospective randomized controlled study included 256 patients subjected to flexible ureteroscopy (FURS) for ureteral or renal stones from March 2018 to July 2022. Treatment groups included the standard antibiotic prophylaxis group (group 1, n=128) and the enhanced prophylaxis group (group 2, n=128). Patients in group 1 were injected with intravenous fluoroquinolone one hour preoperatively, and oral antibiotics were used for 24 h postoperatively. Patients in group 2 had urine culture ten days before the procedure; antibiotic-culture based was given for positive asymptomatic cases, while the procedure was deferred for active UTI. Results: The study groups were comparable regarding patient demographics, stone characteristics, operative time, and intraoperative complications. The overall hospitalization time was 1.68 ± 0.81 days. Postoperative, and overall complications were significantly higher in group 1 (15.6% vs. 6.3%, p = 0.04 and 26.6% vs. 17.2%, p = 0.047), respectively. Twenty patients (15.6 %) in the standard prophylaxis group were diagnosed with UTI in comparison to 8 patients (6.3 %) in the enhanced prophylaxis group (p = 0.047). Conclusions: Urinary tract infection after FURS could be reduced significantly by utilizing the suggested enhanced prophylactic approach.

    Abstract: Background: General anesthesia in high-risk patients has many complications and needs long preoperative preparations and postoperative intensive care unit (ICU). Therefore the present study aimed to evaluate the efficacy of combined low-dose spinal anesthesia with quadratus lumborum block (QLB) as an alternative to general anesthesia for patients undergoing percutaneous nephrolithotomy. Patients and methods: A prospective study was conducted at the urology department of Al-Azhar University Hospitals in Cairo, Egypt, from January 2021 to January 2022. The study included 60 patients of ASA ll-lll scheduled for percutaneous nephrolithotomy. All patients received low-dose spinal anesthesia (5 mg bupivacaine) and QLB (QL1-QL2-QL3) approaches. The primary observation parameter was the efficacy of this technique as an alternative to general anesthesia. The secondary parameters measured were evaluation of need for intraoperative narcotics, postoperative pain score (VAS), and patients satisfaction as assessed using a 5-point Likert Scale. Results: None of the patients was given general anesthesia, and intraoperative sedation was given to nineteen patients (32.2%). No hemodynamic changes were observed in all patients. There was a significant correlation between the use of intraoperative sedation and stone site, intraoperative blood loss, and hospital stay. Pain intensity on VAS at rest and movement was low until the 24th postoperative hour. Patient satisfaction score was 3, 4, and 5 in 1 (1.7%), 4 (6.7%), and 55 (91.6%) patients, respectively. Conclusions: Combined low-dose spinal anesthesia with quadratus lumborum block is an effective alternative to general anesthesia in patients undergoing PCNL procedures with good postoperative analgesia. Patients with lower calyceal punctures have a lower incidence of intraoperative sedation requirements.

    Abstract: Learning curve of laparoscopic nephrectomy (LN) is mainly affected by two main factors: plotting performance and experience. However, there is paucity in the literature addressing the number of cases required to adopt LN. Herein, we aimed to assess the learning curve of LN for various renal disorders and number of cases required to adopt the technique. Between September 2015 and December 2017, consecutive patients undergoing LN for various renal diseases were enrolled in this study. Patients were divided into two groups, the first 20 cases (group A) and subsequent 20 cases (group B). All procedures were performed by a single trainee urologist under supervision of an expert endourologist. Learning curve was assessed using operative time and incidence of complications. Results A total of 40 patients were included in this pilot clinical study. Mean age was 38.2 ± 16.3 years. The mean operative time for patients in group B was significantly lower than the mean operative time for patients in group A (108.5 vs. 139.3 min, p   〈  0.05). However, there were no significant differences between both groups in terms of intraoperative blood loss (86 vs. 104 ml; p  = 0.081), conversion to open surgery (5% vs. 10%; p  = 0.256) and postoperative complications (5% vs. 15%; p  = 0.09) for group B and group A, respectively. Similarly, there was no significant difference between both groups in terms of hospital stay (42 ± 8 vs. 46 ± 11 h p  = 0.01). The trainee surgeon reached a plateau after 22 cases. Conclusions Our study suggests that a minimum of 22 LN procedures are needed in order to adopt the technique of laparoscopic nephrectomy. Learning curve of LN is mainly affected by number of performed procedures within a short period of time.

    Abstract: To evaluate the role of preoperative UWT in the prediction of impaction of ureteral stones stratified according to stone size in ureteroscopic laser lithotripsy. Patient and methods This study included 154 patients submitted to URSL for ureteral stones. Radiological data comprised the presence of hydronephrosis, anteroposterior pelvic diameter (PAPD), proximal ureteric diameter (PUD), and maximum UWT at the stone site. Collected stone characteristics were stone size, side, number, site, and density. Results The study included 154 patients subjected to URSL. They comprised 74 patients (48.1%) with impacted stones and 80 (51.9%) with non-impacted stones. Patients were stratified into those with stone size ≤ 10 mm and others with stone size  〉  10 mm. In the former group, we found that stone impaction was significantly associated with higher PAPD, PUD, and UWT. In patients with stone size  〉  10 mm, stone impaction was related to higher UWT, more stone number, and higher frequency of stones located in the lower ureter. ROC curve analysis revealed good power of UWT in discrimination of stone impaction in all patients [AUC (95% CI) 0.65 (0.55–0.74)] at a cut-off of 3.8 mm, in patients with stone size ≤ 10 mm [AUC (95% CI) 0.76 (0.61–0.91)] at a cut-off of 4.1 mm and in patients with stone size  〉  10 mm [AUC (95% CI) 0.72 (0.62–0.83)] at a cut-off of 3.0 mm. Conclusions Stratifying ureteric stones according to size would render UWT a more practical and clinically-oriented approach for the preoperative prediction of stone impaction.

    Abstract: Objective: To quantify the predictors for the ancillary treatments after extracorporeal shock wave lithotripsy (SWL) for renal and upper ureteral stones. Materials and methods: From January 2014 to January 2017, patients undergoing SWL using an electromagnetic lithotripter machine (Compact Delta; Dornier MedTech GmbH, Wessling, Germany) for renal and upper ureteral stones ≤ 20 mm were retrospectively reviewed. All patients underwent CT urography prior to SWL. The cohort was subdivided into three groups according to stone attenuation values in Hounsfield Units (HU). Group I; HU 〈 500 (n = 20), group II; HU 500-1000 (n = 51) and group III; HU ≥ 1000 (n = 180). The parameters included for multivariate analysis were stone size, location, multiplicity, stone attenuation value, number of shocks and stone clearance rate by 3 months. The ancillary treatments were ureteroscopy (URS), ureteral stenting and hospital readmission for pain or fever. Results: A total of 251 patients were included in the study. The overall SWL success rate was 92.4%. Mean stone size was 10.9 ± 2.1, 11.6 ± 3 and 11.4 ± 3.6 mm and mean stone attenuation values were 364 ± 125, 811 ± 154 and 1285 ± 171 HU for groups I, II and III respectively. The stone clearance rates by 3 months were 96%, 92% and 88.4% for groups I, II and III respectively. On subgroup analysis, group III required ancillary treatments in 70% of patients whereas group I, II, did not require any ancillary treatments. On multivariate analysis, stone multiplicity, stone location (lower calyceal stones) and HU were independent significant predictors for the need for ancillary treatments after SWL (p values 〈 0.05). Conclusions: Patients with stone attenuation value (HU) 〉 1000, multiple stones and/or lower calyceal stones have higher risk to necessitate ancillary treatments after SWL. These patients would likely benefit from upfront endoscopic lithotripsy for treating symptomatic renal or upper ureteral stones.

    Abstract: Purpose: To address the pattern of urodynamic findings in diabetic patients with lower urinary tract symptoms (LUTS), comparing short-standing and long-standing type 2 diabetes mellitus (T2DM). Methods: A prospective study was conducted on 50 patients pre- senting with LUTS and a concurrent diagnosis of T2DM, between February 2016 and May 2018. Patients were classified and evaluated according to the duration of diabetes into two groups: short-standing DM ( 〈 15 years, n = 31), and long-standing DM (≥ 15 years, n = 19) groups. The impact of LUTS and quality of life were assessed in female patients using ICIQ-FLUTS and male patients using ICIQ-MLUTS. Results: A total of 50 patients were included in the study. The mean duration of T2DM was 10 ± 0.7 years. The mean age was 56.3 ± 1.2 years, and the mean HbA1c was 7.5 ± 1.2%. Urodynamic evaluation detected significantly higher detrusor overactivity (DO) and increased bladder sensation with the short-standing DM group (35.5 vs. 15.8%, p = 0.01 and 32.3 vs. 5.3%, p = 0.01, respectively). Comparatively, weak, or absent detrusor contractility were more frequent in patients with long-standing DM (52% and 26% respectively p = 0.01). As expected, overflow incontinence and straining during voiding were significantly higher in the long-standing DM group (p = 0.04 and p = 0.03, respectively). Surprisingly, there was no significant correlation between patients presenting with urgency in their voiding diary (subjective) and urodynamic detection of DO (p = 0.07). Conclusions: There are different patterns in urodynamic charac- terizations of T2DM. Patients with short-standing DM present more commonly with storage symptoms and detrusor overactivity on urodynamics. Contrastingly, patients with long-standing DM present more frequently with voiding symptoms and detrusor underactivity on urodynamics. Thus, screening for an underactive bladder is advisable in patients with long-standing T2DM.

    Abstract: To evaluate and compare the outcome of ECIRS in the treatment of partial staghorn renal calculi in both prone split-leg positions versus GMSV positions with regard to; technical aspects, success rate, operative time, complications, safety, and effectiveness of both approaches. Patients and methods: Between October 2018 and August 2021, 66 patients with partial staghorn calculi were enrolled in this prospective comparative study. Patients were randomly divided according to a 1:1 ratio into two groups. Group A included 33 patients who were treated by (ECIRS) in the prone split-leg position, and group B included 33 patients who were treated by (ECIRS) in the Galdakao-modified supine Valdivia (GMSV) position. Results: No significant statistical difference between both groups regarding the mean age (p = 0.448), mean body mass index (BMI) (p = 0.137), mean stone burden (p = 0.435), mean operative time (p = 0.541) and the number of calyces located in branched stones (p = 0.628). The mean hospital stay was 6.71 ± 1.12 days for group A and 6.66 ± 1.10 days for group B patients (p = 0.724). The final SFR was achieved in (29)87.87% and (30)90.9% of group A & B patients, respectively (p = 0.694). No significant difference was detected between both groups in perioperative complication rates. Conclusion: ECIRS is safe and effective in treating partial staghorn calculi either in the prone split-leg position or in the Galdakao-modified supine Valdivia position, with comparable outcomes and no statistically significant difference between both positions.
