Abstract
PURPOSE To compare the oncological outcome of performing ePLND before or after RC in 200 patients in a prospective randomized manner. MATERIALS AND METHODS From January 2014 to December 2019, 200 patients with T2-T3b N0M0 BCa were included in the current study after signing an informed consent. Patients were divided into two groups, 100 in each one. Group I underwent ePLND before RC, whereas group II underwent ePLND after RC. Postoperative evaluation included clinical, laboratory, and radiographic studies. RESULTS Patients' characteristics were comparable between both groups. The mean operative time excluding that of urinary diversion was significantly shorter in group II than in group I (p = 0.01). The mean number of LNs removed was 25 ± 6 in group I and 32 ± 8 in group II (p = 0.141). Intraoperative complications occurred in four patients in the form of external iliac artery and vein injury [two in each group (p = 0. 245)]. Postoperative complications were comparable between both groups with no statistically significant difference (p = 0.375). Oncological failure occurred in 28 patients [16 (17.6%) in group I and 12 (22%) in group II (p = 0.389)]. CONCLUSIONS EPLND before and after RC has comparable oncological outcomes. The stage of the disease, the time since the first diagnosis till RC and the surgeon experience in performing meticulous ePLND are more important. In absence of oncological superiority, the timing of ePLND should be judged according to the patient-related factors to facilitate safe RC with minimal morbidity.

Abstract
OBJECTIVES to assess the functional outcome of performing ureteric re-implantation to an angled short chimney in a modified spiral orthotopic ileal neobladder. PATIENTS AND METHODS From January 2018 to December 2020, 90 male patients with bladder cancer underwent radical cystectomy and spiral ileal neobladder reconstruction with a chimney. Patients were randomly divided in two groups according to the position of the chimney [straight and angled] to which the ureters will be implanted. Postoperative evaluation included clinical, laboratory, radiographic and urodynamic studies. RESULTS There were no perioperative deaths. The mean operative time for the procedure was 4.7 ± 1.2 h in group I and 4.9 ± 1.3 h in group II (p 0.456). No intraoperative complications occurred. Early postoperative complications occurred in 8 patients. In group I, according to the modified Clavien system, GII complication occurred in 2 (5%) patients in the form of DVT in 1 (2.5%) and surgical site infection in 1 (2.5%). GIIIa occurred in 3 (7.5%) patients in the form of wound dehiscence. In group II, GII occurred in 2 (4.8%) patients in the form of prolonged urinary leakage and myocardial infarction, each occurred in one patient. GIIIb occurred in 1 (2.4%) patient in the form of intestinal leak. Poucho-ureteral reflux occurred in 10 patients [3 (7.5%) in group I and 7 (16.8%) in group II (p 0.001)]. CONCLUSIONS The preliminary results of the right sided angled chimney during neobladder reconstruction are safe, acceptable, without an extra time to develop an anti-reflux technique and without an increased incidence of reflux.

Abstract
Introduction Obstructive anuria can be managed by primary ureteroscopy (URS) or deferred URS after initial ureteral stenting. We want to compare the primary URS and deferred URS in the management of calculus anuria regarding the feasibility and clinical outcome. Material and methods Between January 2012 and December 2014, 150 patients with anuria due to ureteral calculi were prospectively randomized according to the timing of ureteroscopic intervention into two groups; deferred URS group (69 patients who were treated initially by ureteral stenting) and primary URS group (81 patients who were treated by emergency URS). Follow-up was at least 6 months postoperatively. Results Complete stone clearance was 87 % and 75.3% for deferred and primary URS groups, respectively (p = 0.097). Renal function normalized in 94.2% of deferred URS vs. 97.5% of primary URS (p = 0.414). Deferred URS group had a 2.9 % overall complication rate in comparison to 9.9 % for the primary URS group (p = 0.109). Ureteral perforation/pyelonephritis was noted in 6.2% of the primary URS group only (p = 0.043). The median number of maneuvers required until stone clearance was one (range 1–5) for primary URS vs. two (range 2–3) for deferred URS (p <0.001). The cost of primary URS was significantly less (p <0.001). On a multivariate analysis, lower ureteral calculi (OR 13.03, 95% CI 4.07– 41.7, p <0.001) and deferred URS (OR 2.84, 95% CI 1.07–7.49, p = 0.035) were independent predictors for an eventless and successful URS. Conclusions Primary URS for calculus anuria is feasible and cost-effective. It has a short hospital stay, but is still technically demanding. The perioperative complications are comparable to URS in normouric patients.

Abstract
In Egypt, bladder cancer is one of the most popular cancers, accounting for 31% of all cancer cases. It ranks first in males about 16.2% of male cancer. The incidence in rural areas among males is near 32 per 100,000. The exact etiology of bladder cancer is still unknown; K-ras gene is known as a critical DNA target for chemical carcinogens such as pesticide. Some occupational hazard exposure is thought to be directly genotoxic, while others might enhance the mutagenicity and carcinogenicity of directly acting genotoxic agents. Analysis of the relationship between pesticide exposure and mutation in the K-ras gene in human bladder cancer. One hundred patients were diagnosed with bladder cancer and two hundred controls attended the outpatient clinic; after taking consent and filling a questionnaire for age, sex, occupation and pesticide exposure, surgically resected specimens were collected and the samples were used to determine the k-ras mutation. Blood samples were taken to analyze the level of acetylcholinesterase enzyme and level of P53. The present study indicated that pesticide exposure may play a great role in malignant transformation of the bladder cells through mutation in the K-ras gene; there was a significant correlation between the acetylcholinesterase enzyme level and k-ras mutation (p < 0.001). The results revealed that the level of P53 was significantly high in comparison with the control group (p < 0.001). These findings give an alarm to decrease the amount of pesticides used in our area; also, p53 may be used as an indicator to bladder cancer.

Abstract
BACKGROUND To compare the results of urethral anastomosis to a button hole and to the lowest part of the anterior suture line during orthotopic neobladder substitution. METHODS From January 2012 to December 2015, 87 consecutive male patients with invasive bladder cancer underwent radical cystectomy and Hautmann ileal neobladder. Patients were randomly divided into two groups; group I (44 patients), the outlet was created as a button-hole at the most dependent part of the pouch, group II (43 patients), the lowest 1 cm of the anterior suture line of the pouch was left open as an outlet. Patients were randomly assigned to either group using computer-generated random numbers (JMP, Version 12.0.1; SAS Institute, Cary, NC, USA) via a sealed envelope. The functional outcomes of both groups were compared especially at the urethro-enteric anastomosis. RESULTS There were no intraoperative complications. Early postoperative complications occurred in 9 patients (5 in group I and 4 in group II, p = 0.484). Prolonged urinary leakage persisted for 11 and 14 days in 2 patients in group I and 10 and 16 days in 2 patients in group II. Delayed postoperative complications occurred in 11 patients (5 [12.5%] in group I and 6 [15.6%] in group II) (p = 0.711). Three patients developed urethro-enteric strictures (2 in group I and 1 in group II) (p = 0.571). CONCLUSION The "non-hole" technique of urethral anastomosis was not associated with a significant increase in the complication rate when compared to the commonly performed "hole" technique.

Abstract
Introduction To assess if the apparent diffusion coefficient (ADC) value of magnetic resonance imaging (MRI) can discriminate between the cell type, histological grade and improve staging of urinary bladder cancer (BC). Material and methods 102 patients with urinary bladder masses underwent MRI using a 1.5 T machine. T2 weighted and diffusion weighted imaging (DWI) using b values of 0, 150, 500 and 1000 s/mm2 were done. The ADC values of bladder masses were measured. These values were correlated with the histopathologic results. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy of T2WI, DWI and T2WI plus DWI for detecting bladder lesions were evaluated. RESULTS The cut-off ADC value for diagnosing malignant bladder wall pathologies was ≤1 x 10-3 mm2/s with 94.5% sensitivity and 87.5% specificity. The mean ADC value of different malignant cell types was statistically insignificant. A significant difference in ADC values was found between G1 and G3 (P = 0.000), G2 and G3 (P = 0.045) but not between G1 and G2 (p = 0.066). Staging accuracy for differentiation between invasive and non-invasive lesions was nearly the same for all MRI data sets. For differentiation between organ confined (pT1–pT2) and non-organ confined lesions (pT3–pT4), staging accuracy was better in T2WI plus DWI (83%) as compared to DWI alone (77%) or T2WI alone (75%). Conclusions Adding DWI and the ADC value to T2WI improve the accuracy of MRI in BC detection and staging. However, at this time point, MRI cannot replace transurethral resection (TUR) biopsy or distinguish sharply between all different histologic grades and cell types.

Abstract
OBJECTIVE The aim of this study was to report the functional outcome after endoscopic management of neobladder complications. MATERIALS AND METHODS Out of 197 patients who underwent radical cystectomy and orthotopic ileal neobladder reconstruction between 2007 and 2013, 30 patients with delayed postoperative complications were enrolled in this study. Complications were in the form of: eight patients with outflow obstruction, 12 with ureteroenteric stricture, nine with neobladder calculi and one with an isolated recurrent papillary tumor inside the neobladder. Patients were followed up regularly to assess the outcomes of endoscopic treatment. RESULTS The mean maximum flow rate and postvoiding residual urine after endoscopic treatment of outflow obstruction were 18.2 ± 3.9 ml/s and 28.7 ± 11 ml, respectively. Ten patients with ureteroenteric stricture showed resolution of hydronephrosis after antegrade dilatation and JJ-stent fixation, with two patients requiring open surgery owing to impassable strictures. Complete clearance of neobladder calculi occurred after endoscopic neocystolithotripsy, with two patients requiring two sessions owing to large calculi. Transurethral resection of the neobladder for isolated tumor recurrence was performed in one patient over two sessions, followed by adjuvant chemoirradiation. CONCLUSIONS Endourological management of orthotopic neobladder problems is the safest choice. It avoids the difficulties and complications of open surgery and has durable results.

Abstract
Background Local pelvic recurrence after radical cystectomy for muscle invasive bilharzial related squamous cell carcinoma accounts for 75% of treatment failures even in organ confined tumors. Despite the proven value of lymphadenectomy, up to 60% of patients undergoing cystectomy do not have it. These factors are in favor of adjuvant radiotherapy reevaluation. objectives: to evaluate the effect of adjuvant radiotherapy on disease free survival in muscle invasive bilharzial related squamous cell carcinoma of the urinary bladder and to test the predictability of radio-sensitivity using the anti apoptotic protein Bcl-XL. Methods The study prospectively included 71 patients, (47 males, 24 females) with muscle invasive bilharzial related squamous cell carcinoma of the bladder (Stage pT2a-T3N0-N3M0) who underwent radical cystectomy in Assiut university hospitals between January 2005 and December 2006. Thirty eight patients received adjuvant radiotherapy to the pelvis in the dose of 50Gy/25 fractions/5 weeks (Group 1), while 33 patients did not receive adjuvant radiotherapy (group 2). Immunohistochemical characterization for bcl-xL expression was done. Follow up was done every 3 months for 12 to 36 months with a mean of 16 ± 10 months. All data were analyzed using SPSS version 16. Three years cumulative disease free survival was calculated and adjusted to Bcl-XL expression and side effects of the treatment were recorded. Results The disease free cumulative survival was 48% for group 1 and 29% for group 2 (log rank p value 0.03). The multivariate predictors of tumor recurrence were the positive Bcl-XL expression (odd ratio 41.1, 95% CI 8.4 - 102.3, p < 0.0001) and radiotherapy (odd ratio 0.19, 95% CI 0.05 - 0.78, p < 0.02). With Cox regression, the only independent multivariate predictor of radio-sensitivity was the Bcl-XL expression with odd ratio 4.6 and a p value < 0.0001. All patients tolerated the treatment with no life threatening or late complications during the period of follow up. Conclusions Adjuvant radiotherapy for muscle invasive bilharzial related squamous cell carcinoma of the urinary bladder has potential effectiveness and minor side effects. Moreover, Bcl-XL expression is a valuable tool for predicting those who might not respond to this adjuvant treatment.

Abstract
INTRODUCTION AND HYPOTHESIS We hypothesized that upward bladder traction by visceral peritoneal closure during cesarean sections may have an impact on postpartum urinary complaints. METHODS Based on a 90% power of the study and a 95% confidence interval, a sample size of 114 patients in each arm was needed to detect a 15% difference between both groups regarding postpartum urinary incontinence. To account for follow-up losses, we prospectively randomized 620 term primigravidas undergoing non-emergency cesareans into two groups (310 each): group 1, visceral peritoneal closure; group 2, non-closure. We compared perineal ultrasound findings 30 min before and 48 h after surgery. The UDI-6 questionnaire was used to assess urinary complaints. RESULTS Group 1 showed significant widening of the posterior urethrovesical angle and alpha angle, more urethral descent 48 h postpartum and higher incidence of frequency, urge and stress incontinence 8 weeks postpartum. Symptoms disappeared almost completely after 6 months. CONCLUSIONS Compared to visceral peritoneal non-closure, cesarean with visceral closure is associated with significant postpartum frequency of urination and/or incontinence that disappear without treatment almost completely within 6 months.

Abstract
Introduction The AUA/EAU Ureteral Stones Guideline Panel reported that the stone free rate for the proximal ureteral stones is around 81% when treated by either SWL or ureteroscopy (URS). Complication rates, most notably ureteral perforation and long-term complications of URS such as stricture formation rates, have been reduced to < 5%. Moreover, impacted ureteral calculi are more difficult to fragment with SWL because of the lack of natural expansion space for stones, this result in a situation that is better managed by ureteroscopy. The aim of this study is to assess the efficacy, safety, and complications of impacted upper ureteral stone disintegration using semirigid ureteroscopes and pneumatic lithotripsy. Methods We retrospectively analyzed the records of 267 consecutive patients with impacted upper ureteral stones (9–20 mm) who were treated by semirigid ureteroscopes and pneumatic disintegration. The efficacy of treatment was estimated using the stone-free rate and all treatment related complications were analyzed. Results Except for 24 cases where the stone migrated to the kidney, the stone was successfully treated ureteroscopically, with a low rate of minimal complications such as mild hematuria (18.4%), short term low grade fever (13.5%). Only 3 patients (1.1%) had high grade fever and none had post operative stricture. Conclusion The use of semirigid URS and pneumatic lithotripsy in impacted upper ureteral stones in experienced hands has very satisfactory results with minimal complications. When Holmium laser and flexible URS are not available, semirigid URS and pneumatic lithotripsy is a good alternative that shouldn't, yet, be abandoned.

Abstract
Background In Egypt, where bilharziasis is endemic, bladder cancer is the commonest cancer in males and the 2nd in females; squamous cell carcinoma (SCC) is the commonest type found, with a peculiar mode of presentation. The aim of this study is to identify and rank the risk factors of muscle invasive bladder cancer (MIBC) in Upper Egypt and describe its specific criteria of presentation and histopathology. Methods This is an analytical, hospital based, case controlled study conducted in south Egypt cancer institute through comparing MIBC cases (n = 130) with age, sex and residence matched controls (n = 260) for the presence of risk factors of MIBC. Data was collected by personal interview using a well designed questionnaire. Patients' records were reviewed for histopathology and Radiologic findings. Results The risk factors of MIBC were positive family history [Adjusted odds ratio (AOR) = 7.7], exposure to pesticides [AOR = 6.2], bladder stones [AOR = 5], consanguinity [AOR = 3.9], recurrent cystitis [AOR = 3.1], bilharziasis [odds ratio (OR) = 5.8] and smoking [OR = 5.3]. SCC represented 67.6% of cases with burning micturition being the presenting symptom in 73.8%. Conclusion MIBC in Upper Egypt is usually of the SCC type (although its percentage is decreasing), occurs at a younger age and presents with burning micturition rather than hematuria. Unlike the common belief, positive family history, parents' consanguinity, exposure to pesticides and chronic cystitis seem to play now more important roles than bilharziasis and smoking in the development of this disease in this area.

Abstract
OBJECTIVES Bcl-2 and Bcl-XL are the most important antiapoptotic members of the Bcl-2 family frequently overexpressed in bladder cancer. Overexpression of Bcl-XL bilharzial-related bladder cancer was associated with tumor progression. However, the negative prognostic value of Bcl-2 expression is still questionable. This work studied the expression of Bcl-XL and Bcl-2 immunohistochemically in bilharzial-related squamous cell carcinoma of the urinary bladder and determined their prognostic value in relation to recurrence after radical cystectomy. METHODS A total of 72 patients with muscle-invasive bilharzial squamous cell carcinoma of the urinary bladder underwent radical cystectomy at our institution. The specimens were examined immunohistochemically for Bcl-XL and Bcl-2 expression. The patients were followed up for 3 years or until recurrence. The expression of Bcl-XL and Bcl-2 were related to the other prognostic indicators and patient survival. RESULTS The expressions of both Bcl-2 and Bcl-XL were significantly different according to the grade of malignancy. Bcl-XL expression was significantly related to tumor recurrence, but Bcl-2 expression was not. CONCLUSIONS To our knowledge, the present study is the first report of a negative prognostic value for Bcl-XL in bilharzial squamous cell carcinoma of the urinary bladder. However, this is another negative report on the prognostic value of bcl-2 in bilharzial bladder tumors.

Abstract
INTRODUCTION AND AIMS Being best-studied superficial bladder cancer (SBC) chemopreventives, retinoids' negative studies and toxicity were stumbling. With proper understanding of retinoid metabolism, we aimed at investigating combined ketoconazole (a strong inhibitor of retinoic acid-catabolizing cytochrome P450s) all-trans retinoic acid (Keto-atRA) SBC treatment. VEGF and TGFalpha levels are end-point pathogenetic biomarkers involved in early SBC. RESULTS Keto-atRA treatment significantly improved survival time and decreased recurrence rate compared to control disease group, with tolerable and reversible side-effects. Treatment normalized induced levels of VEGF and TGFalpha with a positive correlation between these cytokines. MATERIAL AND METHODS Seven days after TURT visible tumor(s), combined atRA 1 mg/kg for five days a week + Keto 200 mg twice daily for five days a week for three months were given to 16 patients with SBC stages Ta and T1 with various grades. Three months follow up/20 months used white light cystoscopy and urinary cytology. Recurrence rate and survival time were compared to a retrospective group of 25 patients of comparable age, stage and grade with TURT as sole treatment for SBC. VEGF and TGFalpha were measured in urine and serum of 12 normal subjects and treated patients. Samples were collected just before TURT, one week after TURT, at the end of one month and at the end of three months of treatment. CONCLUSIONS The combination and schedule used for Keto-atRA therapy effectively reduced recurrence rate and increased survival time of SBC patients probably through reduction of VEGF and TGFalpha as major mitogenic/angiogenic factors; possibly by eliminating malignant cells that produce them.
