Objective: This study aimed to evaluate the feasibility of the fluoroscopy-free single-use flexible ureteroscopy procedure in the treatment of kidney stones with abnormal renal anatomy compared to normal renal anatomy. Methods: Forty patients with abnormal (Group A) and 80 patients with normal (Group B) renal anatomy who had 10-20 mm renal stones were included. They were treated with LithoVue single-use flexible ureteroscopy (Boston Scientific, Marlborough, MA, USA) after ureteric dilatation by two different size semi-rigid ureteroscopes. This technique was chosen as the aim was to exclude any ureteric pathology (e.g., stone or stricture), confirm the placement of a safe guidewire, avoid balloon dilatation of the ureter, and achieve safe insertion of a 12 Fr, 35/45 cm ureteric access sheath with optical and tactile sign and without fluoroscopy image for guidance. Results: The mean ages were 43 years and 45 years in Group A and Group B, respectively. The mean stone burden was 14.62 (standard deviation: 5.35) mm(3) and 14.79 (standard deviation: 4.58) mm(3) in Group A and Group B, respectively. There is no significant difference between both groups according to the mean operative time, hospital stay, or stone-free rate. The stone-free rate was about 93% in both groups when the stone size was between 10 mm and 15 mm, and less than 54% when the stone size was more than 15 mm to 20 mm. In the majority of cases (80.0% in Group A and 92.5% in Group B), we completed the procedure without fluoroscopy. The perioperative complication rates were comparable in the two groups. Conclusion: Fluoroscopy-free single-use flexible ureteroscopy, when performed by expert urologists, is a feasible treatment for pre-stented patients with kidney calculi of <= 15 mm with abnormal renal anatomy.

Purpose: Retrospective comparative study of the efficacy of extravesical non-dismembered common sheath ure-teral reimplantation (ECSR) versus intravesical common sheath ureteral reimplantation (ICSR) techniques for the correction of vesicoureteral reflux (VUR) in complete duplex systems. Material and Methods: Between 2010 and 2019, ECSR was performed in 38 children (8 bilaterally), and the mean ages at presentation and at surgery were 31 and 57 months, respectively. The ICSR technique was performed in 25 units (25 patients). Voiding cystography and ultrasound of the kidney and bladder were performed 3 and 12 months postoperatively. We analyzed the surgical outcomes for both groups. Results: The mean follow-up times for the ECSR and ICSR groups were 15 and 18 months, respectively. The success rate of the ECSR group was 93.5% at 3 months, improving to 95.7% at an average of one year; the rate of the ICSR group was 96% at 3 months and was the same after one year, with no significant difference between the two groups (p = .66). Postoperative complications were compared in the ECSR and ICSR groups: transient con-tralateral VUR was seen in 5 renal units versus 4, de novo hydronephrosis was seen in 3 units versus 2, and UTIs were observed in 3 patients versus 4. Conclusion: Both (ECSR) and (ICSR) surgeries are highly successful for the correction of VUR in uncomplicated complete duplex systems. The results of the extravesical approach are comparable with those of the intravesical technique with less morbidity and a shorter hospital stay. Thus, ECSR is our preferred technique when open surgical repair is indicated. ICSR should be reserved for complicated duplex systems necessitating concomitant reconstructive surgery.

Background and purpose: Benign prostatic hyperplasia (BPH) is the most common urologic disorder affecting older men, necessitating medical or surgical intervention. Limited data exists regarding the effect these surgeries have on the endourologist’s musculoskeletal system following the surgery because of the required difficult posture, prolonged procedures, repetitive movements, and the settings of an adjustable visual display terminal workstation. The aim of our study was to survey the prevalence and possible causes of musculoskeletal disorders among endourologists performing transurethral resection of the prostate (TURP) or laser prostatectomy using either holmium laser enucleation or thulium laser enucleation. Materials and methods: An email inviting all members of the Endourological Society to participate in the survey was sent. The questionnaire included different demographic and practice characteristics, with concern regarding performing either TURP or laser prostatectomy and the incidence and type of musculoskeletal incidents following these surgeries. All responses were collected by a commercially available internet based survey host ( www.surveymonkey.com ) over a period of 6 weeks. Results: Of the 121 complete responses, 84 (69%) of endourologists complained of a musculoskeletal disorder following TURP or laser prostatectomy. The most frequent complaint was for neck (64%), followed by back (57%), shoulder (48%), hand (40%), and elbow (18%). The average prostate volume turned out to be the most compelling predictor for musculoskeletal disorder occurrence with an average prostate volume of 76 g operated on by the complaining group compared with 59 g in the noncomplaining group. Those with more severe symptoms were linked to a mean prostate size of 80 g (60–146) and constantly complained of shoulder, neck, or back trouble compared with the less-severely complaining group. Conclusions: A high prevalence of musculoskeletal complaints among urologists performing endourologic prostatectomy was confirmed and was found to be proportionally related to the size of the prostate. The integration of an ergonomic specialist inside the operation room to watch and correct the surgeon’s position during endourologic procedures may reduce the endourologist’s exposure to these occupational hazards.

Background: Transurethral resection of tumor is the main treatment of non-muscle-invasive urothelial carcinoma, but it is associated with high rate of recurrence and/or progression and this arouses the need for adjuvant therapy. Topoisomerase II (Top II), KI-67, and P53 are proliferation and cell cycle regulation markers that may predict tumor response to therapy. Aim: This study aimed to assess Top II, KI-67, and P53 expression and their effect on clinical outcome and response to therapy of non-muscle-invasive urothelial carcinoma. Materials and Methods: Fifty cases of non-muscle invasive urothelial carcinoma were collected; Top II, KI-67, and P53 expression was evaluated. Patients received treatment then tumor recurrence was correlated with the expression of previous markers. Results: There was a significant association between high Top II score, P53, and KI-67 and high tumor grade (P = 0.0001, 0.001, and 0.0001), submucosal infiltration (P = 0.0001 and 0.01), and recurrence (P = 0.01, 0.001, and 0.001). Conclusion: Top II, P53, and KI-67 may predict tumor response to therapy and the clinical outcome in non-muscle-invasive urothelial carcinoma.

Context: Spontaneous forniceal rupture is one of the possible complications of urolithiasis. The mechanism of forniceal rupture is not well explained in the literature. Most of the cases presented with sudden onset of acute renal colic and diagnosed by noncontrast CT (NCCT). Until now there is no solid consensus about the ideal management of such a condition. Aim: To study indications and validity of conservative management of spontaneous caliceal rupture. Settings and Design: This is an observational prospective study. Materials and Methods: All cases diagnosed as spontaneous forniceal rupture in our departments from 2011 to 2015 were enrolled. All cases were diagnosed with NCCT or CT-Urography.. Non complicated patients were primarily managed conservatively. Intervention (DJ stent insertion, nephrostomy tube insertion, or urgent ureteroscopy) was reserved to complicated cases or solitary kidney. Drainage of urinoma was done in cases with sizable urinoma (more than 100 ml3). Results: A total of 40 patients: Twenty eight (70%) patients had normal serum creatinine level at presentation, while 12 (30%) patients had elevated serum creatinine. Twenty three (57.5%) patients were successfully managed conservatively, their mean size of stone was 6.2 ± 2 mm and the hospital stay was 3.1 ± 1.9 days. Eighteen patients (42.5%) underwent interventions. Their stone size was 4.5 ± 2.1 mm and the hospital stay for the interventional group was 4.2 ± 1.8 days. Statistical Analysis Used: Mann-Whitney test was used for testing difference between means because the data groups are not parametric. Otherwise, simple descriptive statestics were used. Conclusion: Spontaneous forniceal rupture is more likely to occur with smaller distal ureteric stones. Conservative management is a valid option in non-complicated cases. Intervention should be reserved to complicated cases or cases with sizable urinoma.

OBJECTIVES:To evaluate the presence of balanitis xerotica obliterans (BXO), clinically and pathologically, in the urethra of boys with failed previous hypospadias repair and where surgical management was planned. PATIENTS AND METHODS:Between February 2010 and March 2015, boys with failed distal penile hypospadias repair who were planned for surgical management were evaluated for the presence of clinical and pathological evidence of BXO. Samples were obtained from the urethral plate and fossa navicularis, after obtaining informed consent and ethical approval. The samples were fixed, sectioned, and haematoxylin and eosin stained for light microscopic examination. RESULTS:In all, 157 boys were enrolled in our study, with a mean (SD) age of 6.4 (2.8) years. All the boys had a history of failed hypospadias repair surgeries (once or more). The presentation was fistula in 34 boys (21.7%), meatal stenosis in 45 (28.7%), urethral stricture in 28 (17.8%), and total dehiscence in 50 (31.8%). BXO was detected clinically in 46 boys (29.3%). The total number of biopsies taken was 314, of which 124 (39.5%) were pathologically BXO-positive samples. Of the 157 boys, BXO-positive cases were clinically associated with fistula in seven boys (4.5%), meatal stenosis in 18 (10.8%), urethral stricture in seven (4.5%), and total dehiscence in 15 (9.6%). Of the 314 pathological samples, pathologically BXO-positive samples were associated with fistula in 20 samples (6.4%), meatal stenosis in 40 (12.7%), urethral stricture in 22 (7%), and total dehiscence in 42 (13.4%). CONCLUSIONS:In failed hypospadias cases BXO should be considered, especially for cases with multiple failures, meatal stenosis, and total dehiscence. Urethral plate and fossa navicularis biopsies are important in planning a proper approach for subsequent repair.

Background: Fournier’s gangrene (FG) is an acute progressive necrotizing fasciitis of the genital area and perineum with possible extension to the abdominal wall. Surgical debridement is the gold standard management modality of established patients. Equivocal (early) FG represents a challenge in diagnosis. The objective of this study was to compare conservative management and early exploration in cases of equivocal (early) FG. Methods: This was an observational study where data of all patients diagnosed as early FG in our departments over 4 years (2011–2015) were enrolled. Patients were divided into two groups: group 1 with conservative treatment, and group 2 managed with urgent exploration with longitudinal hemiscrotal incision starting from external inguinal ring. All patients’ demographics, vital signs, laboratory finding and clinical findings were reported. Results: A total of 28 patients were enrolled in the study. Group 1 was managed with conservative treatment (17 patients) and group 2 underwent urgent exploration (11 patients). Overall, four patients (23.5%) out of 17 patients of group 1 showed a good response to conservative management without any surgical debridement. A total of 13 patients (76.5%) developed gangrenous discoloration and needed surgical debridement later. In group 2, four patients (36.4%) underwent scrotal exploration and release incision only without debridement and showed an excellent clinical outcome. A total of four patients (36.4%) underwent debridement with excision of doubtful deep subcutaneous and fascial tissues. The remaining three patients (27.2%) underwent debridement of necrotic fascia. The hospital stay was significantly shorter in group 2 patients than group 1 (7.5 ± 3.75 versus 13.4 ± 5.19 days p < 0.05). The mean number of debridement sessions was 3.74 ± 0.69 in group 1 versus 1.82 ± 0.34 in group 2. Conclusions: Early exploration and debridement in equivocal (early) FG has a better clinical outcome with reduced hospital stay and number of debridement sessions than conservative treatment with delayed debridement.
