Plasma metadherin mRNA expression in bladder cancer.

Urinary bladder cancer (BC) is the ninth most common cancer worldwide. At present, the clinical diagnosis of BC depends on self-reported symptoms, tissue biopsy specimens by cystoscopy and from voided urine cytology. However, cystoscopy is an invasive examination and voided urine cytology has low sensitivity, which might provoke misdiagnosis. The search for cancer biomarkers in blood is worthy of intense attention due to patients' comfort and ease of sampling. This work aimed to study expression of mRNA metadherin (MTDH) in plasma, serum BC specific antigen 1 (BLCA-1) and cystatin C as biomarkers of BC and their relation to different disease stages. This study included 59 BC patients, 11 patients with benign bladder lesion and 18 subjects as normal controls. MTDH expression was assessed by real time polymerase chain reaction, BLCA-1, and cystatin C by the enzyme linked immunosorbent assay. The three biomarkers were elevated in BC patients than patients with benign bladder diseases and controls. Patients with BC grade 3 and 4 had higher cystatin C, BLCA-1 and MTDH in comparison to patients with grade 1 and grade 2 (p=0.000). The receiver operating characteristic curve analysis showed that BLCA-1 at a cutoff point of 32.5 ng/ml and area under the curve of 1.00, had 100% accuracy, 100% sensitivity, 100% specificity, 100% positive predictive values and 100% negative predictive value. In conclusion, BLCA-1 was a better biomarker than cystatin C and MTDH. Cystatin C, BLCA-1 and MTDH levels, can differentiate between benign bladder lesion and BC and correlated with tumor grades.especially with OL-HDF compared to HF-HD, with acceptable albumin loss in the dialysate.

Lymphadenectomy before and after radical cystectomy: does this affect the radicality? A prospective randomized comparative study.

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.

The safety and efficacy of ultrasound versus fluoroscopic percutaneous nephrostomy: A prospective randomized study.

Objective: The objective of this study is to compare the outcome of percutaneous nephrostomy by ultrasound (US) versus fluoroscopy including access time, volume of anesthesia required, success rate, and complications. Methods: One hundred patients were enrolled in a prospective randomized study. Patients were divided into two groups, 50 cases each. Comparing the two groups was done regarding the need for dye, radiation effect, time taken, trial number, rate of complication, volume of anesthesia, and success rate. Results: Patient demographics were comparable between both groups with no statistically significant difference. According to the modified Clavien-Dindo classification, the complications were Grade I (pain and mild hematuria) in each group. Procedural pain was present in 41 (82%) patients in Group I and in 48 (96%) patients in Group II. It was treated in both groups with a simple analgesic. Mild hematuria was present in 5 (10%) patients in the US group and 13 (26%) in the fluoroscopic group and treated by hemostatic drugs only. There was a statistically significant difference between both groups regarding the volume of required local anesthesia, the trial numbers, the puncture numbers, bleeding, extravasation, and change in the hemoglobin level. Conclusion: US percutaneous renal access is a safe and effective modality with a high success rate, less operative time, and complication rate. However, a minimum of 50 cases with some pelvicalyceal system dilation may be preliminary requisites to achieve good orientation and competence in achieving safe US percutaneous renal access for future endourological procedures.

Ileal conduit versus single stoma uretero-cutanoustomy after radical cystectomy in patients ≥ 75 years; which technique is better? a prospective randomized comparative study.

PURPOSE: To compare the clinical results and patients' health-related quality of life (HR-QoL) of ileal conduit (IC) versus single stoma uretero-cutanoustomy (SSUC) after radical cystectomy in two groups of randomly selected patients ≥ 75 years. METHODS: From January 2013 to March 2018, 100 patients ≥ 75 years with muscle invasive BCa underwent RCX and cutaneous diversion. Patients were divided in two groups; group I underwent IC (50 patients) and group II underwent SSUC (50 patients). Postoperative evaluation included clinical, laboratory, radiographic and HR-QoL. The latter was performed using the Functional Assessment of Cancer Therapy-Bladder Cancer (FACT-BL) after 12 months postoperatively. RESULTS: Patients' characteristics were comparable between both groups. No intraoperative complications occurred. Early postoperative complications occurred in 27 patients [16 (35.5%) in group I and 11 (23.9%) in group II (p = 0.02)]. Delayed postoperative complications occurred in 26 patients [6 (13.3%) in group I and 20 (43.4%) in group II, (P = 0.002)]. No significant differences between both groups regarding the physical, social/family, emotional, functional and additional concerns scales of FACT-BL questionnaire were reported. CONCLUSION: SSUC is a good alternative to IC in elderly frail patients ≥ 75 years and those with multiple comorbidities who require rapid surgery in terms of perioperative complications and HR-QoL. However, the stomal complications and the possibility of a frequent stent exchange are considered its drawbacks.

Functional evaluation of a spiral neobladder with an angled chimney; A prospective randomized comparative study.

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.

Experience of a Tertiary-Level Urology Center in Clinical Urological Events of Rare and Very Rare Incidence. V. Urological Tumors: 1. Adrenal Myelolipoma.

OBJECTIVES: To present our center's experience in the management of adrenal myelolipoma in the context of shifting from the open to the laparoscopic adrenalectomy approach. MATERIALS AND METHODS: A retrospective search of our center's records was done for reported cases of adrenal myelolipoma during the period July 2001-June 2016. All the cases with histopathologically-documented adrenal myelolipoma diagnosis were included. Relevant demographic and clinical variables were studied with a comparison between the open and laparoscopic approaches. RESULTS: Of more than 82,000 urological surgeries, 238 adrenalectomies were done with only 22 cases of myelolipoma that had a mean age and body mass index of 52.4 ± 10.3 years and 30.23 kg/m2, respectively. The main clinical presentation was accidental discovery. The largest dimension of tumors varied from 6 to 16 cm. Computed tomography described a characteristic picture of hypodense heterogeneous adrenal tumors in all cases, while magnetic resonance imaging was indicated for malignancy suspicion in only 5 cases. Adrenal tumor markers were normal in all cases. Open and transperitoneal laparoscopic adrenalectomies were used in 14 and 8 cases, respectively. The latter approach was insignificantly advantageous in the need for blood transfusion, postoperative pain degree, need for analgesia, and hospital stay duration (p = 0.22). Histo-pathological examination revealed benign adipose tissue and myeloid cells and confirmed the diagnosis of adrenal myelolipoma in all cases. CONCLUSIONS: Adrenal myelolipoma is a rare non-functioning benign tumor. Laparoscopic excision seems to be a promising alternative approach to the traditional open adrenalectomy, even in the context of large tumors and obesity.

Comparative Application of Different Substaging Techniques for Non-Muscle Invasive Urothelial Carcinoma.

To evaluate the diagnostic performance and clinical significance of 4 systems of substaging cases with non-muscle invasive urothelial bladder carcinoma. In addition 4 cutoff measures were evaluated for prediction of muscularis-mucosa invasion. Four substaging systems were applied to 57 NMIBC cases to assess which of these reported methods correlates best with recurrence and progression. On univariate regression analysis patients having tumor size more than 3 cm, solid tumor architecture, high grade, substage B, substage T1e, substage ROL 2 and Tumor depth more than 1 mm were associated with higher recurrence. On multivariate analysis all the four substaging systems, tumor size, grade and tumor type had significant prognostic value for recurrence. Regarding progression only the metric substaging method was associated with tumor progression (p = 0.04). However, on univariate and multivariate regression analysis none of the substaging systems showed prognostic significance and only solid tumor architecture and CIS had significant prognostic value for tumor progression. The ROC curve analysis showed that 1 mm depth of invasion had the best accuracy for detection of muscularis-mucosa invasion (80.2%). Using 1 mm cutoff in measuring the depth and 0.5 mm for the diameter of infiltration may provide clinically relevant information to guide a more personalized therapy for NMIBC. Inclusion of both measures in addition to other histopathologic variables may aid in the development of a scoring system.

Percutaneous nephrolithotomy versus shock wave lithotripsy for high-density moderate-sized renal stones: A prospective randomized study.

CONTEXT: The management of renal stones of high density (>1000 Hounsfield units) on non-contrast computed tomography (NCCT), and moderate sized (15-25 mm) is still debatable. AIMS: The aim of this study was to compare the outcomes of percutaneous nephrolithotomy (PCNL) and shock wave lithotripsy (SWL) for the high-density and moderate-sized renal stones regarding the stone-free rate (SFR), morbidity, and patients' quality of life. SETTINGS AND DESIGN: This is a prospective randomized study. PATIENTS AND METHODS: Eighty consecutive patients with renal stones, excluding those with lower calyceal stones, were randomized to receive either PCNL or SWL (40 in each arm). Patients were followed up by abdominal ultrasound and plain X-ray (NCCT if indicated) till clearance of stone. Outcomes, complications, costs, and SF-8 Health Survey scoring were recorded for each group. STATISTICAL ANALYSIS: We used Stata software, version 9.2 (Intercooled STATA®; StataCorp LP College Station, Texas, USA). Comparison of the two groups was made with regard to patient and stone criteria and the procedure details. Continuous variables were compared using the Mann-Whitney U-test with values shown as the median and interquartile range. Categorical variables were compared using the Pearson's Chi-square/Fisher's exact test. Multivariate logistic regression analysis was used to identify variables independently associated with the stone clearance after two sessions of SWL. P < 0.05 was considered statistically significant. RESULTS: The basic characteristics of both groups were comparable. After a single treatment session, the SFR was 80% and 27.5% for PCNL and SWL, respectively (P < 0.001). The overall 3-month SFR was 87.5% versus 90%, respectively (P = 0.723). The median number of the required maneuvers was 1 (range: 1-3) for PCNL versus 2 (range: 1-4) for SWL (P < 0.001). The complication rate was 10% and 7.5%, respectively (P = 0.692). The cost of SWL was significantly lower (P < 0.001). On multivariate analysis, a single stone was an independent predictor for stone clearance after two sessions of SWL (odds ratio: 7.26, 95% confidence interval: 1.13-46.62, P = 0.037). CONCLUSIONS: PCNL for the dense, and moderate-sized renal stone provides higher initial success and lower re-treatment rates compared with SWL with comparable outcome after 3 months of therapy. However, SWL is an alternative, especially for a single stone.

Usage of Intravenous Lidocaine Infusion with Enhanced Recovery Pathway in Patients Scheduled for Open Radical Cystectomy: A Randomized Trial.

BACKGROUND: Intravenous lidocaine infusion (IVLI) reduces postoperative pain and hastens the return of bowel function. OBJECTIVES: We aimed to compare the effects of adding lidocaine infusion to enhanced recovery pathway (ERP) on acute rehabilitation protocol. STUDY DESIGN: This study uses a double-blind, randomized design with allocation concealment in a 2-armed parallel group format among patients undergoing open radical cystectomy (RC). SETTING: The study was conducted at Assiut University Hospital, Asyut, Egypt. The study duration was March 2017 to July 2018. METHODS: After ethics committee approval, 111 patients, American Society of Anesthesiologists (ASA) physical status II-III, aged 45-65 years, scheduled for open RC with urinary diversion under an ERP, were randomly selected in a double-blind manner to receive IVLI 2 mg/minute for 4 hours or an equal volume of normal saline solution 0.9%. Postoperative pain scores, rescue analgesic consumption, times to return of bowel sounds, first flatus, first defecation, resuming of regular diet, length of hospital stay, in-hospital complications, and patient satisfaction were recorded. RESULTS: Patients in the lidocaine group experienced significantly lower pain scores after surgery at 6 hours (P = 0.005) and 12 hours (P = 0.001) at rest, and in the first 18 hours during mobilization (P < 0.05), with less paracetamol (P = 0.04) and meperidine (P = 0.02) consumption than in the control group. Between the lidocaine and the control group, mean times to return of bowel sounds (23.7 vs. 26.7 hours; P = 0.001), first flatus (76.5 vs. 86.5 hours; P = 0.001), first defecation (92.7 vs. 106.9 hours; P = 0.001) and resuming of regular diet (80.7 vs. 92.8 days; P = 0.001) were significantly shorter in the lidocaine group. Length of hospital stay, in-hospital complications, and patient satisfaction were similar in both groups. LIMITATIONS: Limitations of this study include lack of previous research that compare the additive effects of IVLI to ERP in patients undergoing open RC. Also, the inability to measure the serum lidocaine concentration in our patients. CONCLUSIONS: Adding IVLI to ERP improved postoperative analgesia and bowel function after open RC with urinary diversion. CLINICAL TRIAL REGISTRATION: NCT03047057. KEY WORDS: Lidocaine infusion, ileus, enhanced recovery pathway, acute rehabilitation, open radical cystectomy.

Health related quality of life after urinary diversion. Which technique is better?

OBJECTIVE: To compare quality of life (QoL) after urinary diversion (UD) following radical cystectomy (RC) using validated questionnaires. PATIENTS AND METHODS: Between January 2011 and June 2016, 150 patients (121 men [80.7%] and 29 women [19.3%]) with invasive bladder cancer who underwent RC and UD were included in this prospective study. Patients were divided into 2 groups; group I included the orthotopic neobladder 50 (33.3%) and uretro-sigmoidostomy 41 (27.3%) and group II included uretero-cutanoustomy 33 (22.1%) and ileal conduit 26 (17.3%) patients. QOL was evaluated using the Functional Assessment of Cancer Therapy-Bladder Cancer. The erectile function (EF) was assessed using the Sexual Health Inventory for Men Questionnaire. Evaluation was done before and after one year postoperatively. RESULTS: The mean ±â€¯SD patient age was 55.0 ±â€¯7.9 and 59.5 ±â€¯8.5 years in both groups, respectively (p = 0.001). There was a significant difference in the physical, social/family, emotional and functional statuses that were significantly higher in group I. One year postoperatively, the emotional well-being became insignificantly different, but other QoL parameters remained significantly different between both groups. Regarding EF, there was a significant difference between patients who underwent nerve-sparing (No. 29) and non nerve-sparing RC (No. 59) (p < 0.001). CONCLUSIONS: Which type of diversion is the best is still a controversial topic. Egyptian patients may prefer the continent UD to avoid the urostomy appliance and its associated daily-life constraints. Detailed patient counseling and active participation of the patient in selecting the treatment methods are important for better postoperative QoL.

Experience of a Tertiary-Level Urology Center in the Clinical Urological Events of Rare and Very Rare Incidence. VI. Unusual Events in Urolithiasis: 1. Long-Standing Urethral Stones without Underlying Anatomical Abnormalities in Male Children.

OBJECTIVES: The study aimed to present our center's experience with long-standing urethral stones in male children with normal urethra. MATERIALS AND METHODS: Retrospective search of our center data was done for the cases of long-standing urethral stones with normal urethra in male children during the period July 2001 - June 2016. Demographic and clinical data were studied. RESULTS: Of more than 54,000 urolithiasis procedures, 17 male children (0.031%) were operated for long-standing urethral stones with normal urethra. In 14 cases (82.4%), residence was rural and parental education levels were low or none. All children were regularly prompted voiding with a history of difficulty or dysuria. All the stones lodged in the posterior urethra with an approximate mean duration of 2 months. The mean stone size of 11.29 ± 3.88 mm and rough surfaces in 88.2% of cases represented the main predisposing factors. Major complications included rectal prolapse in 1 case and vesicoureteral reflux in 3 cases. Endoscopic push-back was followed by disintegration in 76.5% or cystolithotomy in 17.7%, while it failed in 1 case that was treated by cystolithotomy. CONCLUSIONS: Long-standing urethral stones in male children with normal urethra are very rare misdiagnoses. Stone topography and sociocultural factors predisposed to their lodgments and negligence. Endoscopic treatment is the best approach.

Diffusion weighted magnetic resonance imaging in bladder cancer, is it time to replace biopsy?

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.

Experience of a Tertiary-Level Urology Center in the Clinical Urological Events of Rare and Very Rare Incidence. III. Psychourological Events: 1. Psychic Anuria.

INTRODUCTION: Psychic anuria is an old term, referring to a very rare psycho-urological event that has scarcely been studied so far. MATERIALS AND METHODS: A retrospective study of the patients with psychic anuria presented to Assiut Urology and Nephrology Hospital during the period July 1991-June 2016 was done. Psychic anuria was defined, and the demographic and clinical characteristics including the methods of diagnosis and management were studied. RESULTS: Of more than 3,800 cases of anuria, 9 female patients (0.24%) experienced psychic anuria in the age range of 17-43 years. Cardinal clinical findings included anuria for 36-72 h with absence of organic causes and normal renal function tests. Psychosocial risk factors were reported in the 9 cases. Anuria was documented by reliable history (56%) or observable urine collection (44%). Diagnosis was done by exclusion, where the investigations revealed no organic causes. Seven cases responded to the placebo intervention and 2 cases were self-limiting and resolved spontaneously. CONCLUSIONS: Psychic anuria is an extremely rare urological emergency that presents, mainly, in young adult females with unknown mechanisms. Renal vasoconstriction following psychosocial stressors is suggested. It is diagnosed by exclusion and resolves spontaneously or responds to placebo intervention as a mental distraction technique.

Does the site of the orthotopic neobladder outlet matter? A prospective randomized comparative study.

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.

Retroperitoneal Varix ligation with sclerotherapy: a prospective randomized comparative study.

INTRODUCTION: The aim of this article is to compare the results of high varix ligation with and without sclerotherapy. MATERIAL AND METHODS: Between November 2014 and December 2015, sixty patients with varicocele were included in this study. Patients were divided into two equal groups; group I (underwent high varix ligation), and group II (underwent high varix ligation with a retrograde injection of 2 mL of 5% ethanolamine oleate in the lower end of the bisected gonadal vein). The operative time, intra- and postoperative complications, postoperative pain, improvement of semen parameters, incidence of recurrence and achieving of unassisted pregnancy were recorded for both groups. RESULTS: The age range was 19-34 years in group I and 21-37 years in group II. The operative time was shorter in group I (34.6 ±7.81 min) than group II (43.3 ±8.5 min) (P <0.001), which was statistically significant.Improvement of semen parameters and the occurrence of spontaneous pregnancy were insignificant between both groups. No intraoperative complications occurred. The postoperative complications were statistically insignificant in both groups. CONCLUSIONS: Combined varix ligation with retrograde sclerotherapy does not offer significant advantages over high varix ligation alone with a longer operative time and prolonged post-operative pain.

Management of neobladder complications: endoscopy comes first.

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.

The satisfaction of patients with refractory idiopathic overactive bladder with onabotulinumtoxinA and augmentation cystoplasty.

OBJECTIVE: To assess the satisfaction of patients with refractory idiopathic overactive bladder (OAB) with two treatment methods, onabotulinumtoxinA (oBTX) and augmentation ileocystoplasty (AC). PATIENTS AND METHODS: This prospective study included patients with refractory idiopathic OAB for >6 months and a urodynamic diagnosis of OAB. Oral pharmacotherapy had failed in all patients. Patients with any suspected neurological disorder were excluded. Before the procedure, patients completed the Urogenital Distress Inventory (UDI-6) and modified Incontinence Impact Questionnaire (IIQ-7), a neurological evaluation, a urodynamic study and their postvoid residual urine volume was measured. Patients were assigned to receive oBTX or AC, depending on patient's preference. Follow-up visits were at 6 weeks and 3 and 6 months after the procedure. The OAB Satisfaction questionnaire (OAB-SAT-q) was used to assess satisfaction after the procedure. RESULTS: In all, 31 patients with refractory OAB were included, 16 in the oBTX group and 15 in the AC group. There was no significant difference between the groups in mean age, baseline OAB symptoms and urodynamic values. There were significant improvements in urinary symptoms (UDI-6) and quality of life (IIQ-7) after both procedures (except in the domain enquiring about difficulty, which significantly worsened after AC). Of the 16 patients, 15/16 and seven of 15 were completely dry after AC and oBTX, respectively. The overall and individual scores of the OAB-SAT-q were significantly higher among patients treated with AC than with oBTX. The incidence of the de novo need to use clean intermittent catheterisation after oBTX and AC was two of 16 and four of 15, respectively. CONCLUSIONS: Both procedures are effective in improving the symptoms of OAB and of quality of life, but patients were more satisfied with AC than oBTX therapy.
