A scoping review on chordee correction in boys with ventral congenital penile curvature and hypospadias.

Introduction: Congenital penile curvature (PC), often concomitant with hypospadias, poses challenges in urology. Surgical correction techniques, including plication and corporotomy, lack standardized guidelines. This study aims to address the paucity of high-level evidence by comprehensively reviewing the outcomes of PC correction procedures in patients with and without hypospadias. This will inform clinical decision-making and provide insights for future research and meta-analyses. Methods: We conducted this scoping review in accordance with the JBI Manual for Evidence Synthesis and PRISMA-ScR guidelines. An extensive literature search was performed and comparative studies published in English up to June 2023 were included. The studies were divided into three categories: PC without hypospadias, PC with hypospadias, and studies comparing two or more materials for covering the ventral corporotomy. Data extraction comprised author details, patient characteristics, study design, interventions, outcomes, and complications. Methodological quality was assessed using the Newcastle-Ottawa Scale. Results: Forty-two studies were included in the review, which collectively comprised 3180 patients. Thirteen comparative studies reported the outcomes of surgery for congenital PC without hypospadias, 22 studies compared different techniques of PC correction in patients with hypospadias and 7 studies compared the type of materials for coverage following ventral corporotomy. In cases of PC without hypospadias, the most commonly reported surgery was the Nesbit's plication. For PC with hypospadias correction, the results of ventral corporotomy were superior to that of dorsal plication in most of the studies. The two-stage repair had better results when compared to the one-stage repair for patients with perineo-scrotal hypospadias. In studies comparing materials for coverage of ventral corporotomy, the tunica vaginalis flap or graft was utilized most commonly. The majority of the studies reported a success rate ranging from 85% to 100%. The methodological quality was high in all but four studies. Conclusion: Plication procedures are generally preferred for PC without hypospadias, but they result in penile shortening. For those with hypospadias, corporotomy is associated with superior outcomes than plication, especially for those with severe curvature and redo procedures. For ventral corporotomy coverage, the tunica vaginalis flap or graft is the most commonly reported tissue in the literature.

Assessing the Utility of Tamsulosin in Delaying Progression to Clean Intermittent Catheterization and End-stage Renal Disease in Patients With Posterior Urethral Valves: Are We Postponing the Inevitable?

OBJECTIVE: To assess whether tamsulosin may aid emptying of the lower urinary tract in posterior urethral valves patients, mitigating the likelihood of progressing to clean intermittent catheterization (CIC) or need for renal replacement therapy. METHODS: We reviewed a prospective institutional database containing posterior urethral valves patients treated between January 2000 and January 2022. After assessing baseline characteristics, Kaplan-Meier survival curves and log-rank tests were generated to assess differences in clinically significant outcomes (progression to CIC, dialysis, or kidney transplantation) between those prescribed tamsulosin and those who were not. RESULTS: A total of 179 patients were included. Fifty-nine patients received tamsulosin prior to initiation of CIC (group 1), and 120 did not (group 2). The baseline characteristics were similar between the two groups, except for anticholinergic use (tamsulosin group - 35/59 vs no tamsulosin - 32/120, P < .001). The median age at tamsulosin initiation was 26.0 months (IQR 15.5-48.6) and the median time from initiation of tamsulosin to progression to CIC was 52.6 months (IQR 10.1-69.3). Kaplan-Meier survival curves showed that patients on tamsulosin were less likely to progress to CIC (P = .021), however, there was no difference in progression to dialysis or kidney transplantation. A Cox-regression analysis controlling for baseline characteristics, including age, anticholinergic use, vesicoureteral reflux severity, and CKD stage at 1-year of life, showed a consistent effect of tamsulosin in delaying progression to CIC (HR 0.444 95%CI 0.218-0.902, P = .025). CONCLUSION: While tamsulosin may delay CIC, it does not appear to delay progression to end-stage renal disease. Additional studies exploring specific patient factors are required to determine the timing and subset who may benefit the most from tamsulosin.

Comparison of outcomes of prenatal versus postnatal presentation of posterior urethral valves: a systematic review and meta-analysis.

OBJECTIVE: To determine through a comprehensive systematic review and meta-analysis the differences in the outcomes of prenatally versus postnatally diagnosed posterior urethral valves (PUV) to ascertain if prenatal detection of PUV has superior outcomes. METHODS: We conducted a systematic review and meta-analysis in March 2022 (PROSPERO ID - CRD42021243546) and included all studies that reported outcomes of prenatally and postnatally diagnosed PUV. However, for meta-analysis, only those studies that described both groups were included. The main outcomes of interest included progression of chronic kidney disease (CKD), need for renal replacement therapy (RRT) and renal transplant, and bladder dysfunction as determined by initiation of clean intermittent catheterization (CIC). Time to event analyses were completed when possible. RESULTS: The systematic review included 49 studies (3820 patients). The pooled effect estimates for progression to CKD (OR 0.75 [95% CI 0.43, 1.31]), need for RRT (OR 1.39 [95% CI 0.64, 2.99]) and need for renal transplant (OR 1.64 [95% CI 0.61, 4.42]) between prenatal and postnatal groups was not different. CICs rates were as high as 32% in the prenatal group and 22% in the postnatal group. Most studies had a moderate or serious risk of bias. CONCLUSION: The existing comparative literature on prenatal versus postnatal presentation of PUV is very heterogeneous. The diagnostic and treatment protocols have not been reported in majority of the studies. The outcome variables are also reported inconsistently. Based on the current evidence, prenatal diagnosis of PUV does not appear to improve the long-term outcomes of these patients.

Mothers' perception of prenatal counseling following diagnosis of congenital anomalies of the urinary tract.

Congenital abnormalities of the genitourinary tract are the most common sonographically identified malformations. Although prenatal diagnosis seldom modifies perinatal management, it can cause significant anxiety in parents. We aimed to assess how parents perceived the prenatal counseling they had received in our institution. Using a questionnaire, we evaluated by phone the mothers of 78 children diagnosed prenatally with urological tract anomalies between January 2018 and May 2019. Overall, mothers were satisfied and reassured by the prenatal counseling they received, although 19% of the mothers found the time from diagnosis to specialist consultation to be too long. Forty percent of the responders stated that the most important information they needed to hear during the specialist consultation was management and not diagnosis. Specialist counseling should focus on explaining postnatal management, should be offered as soon as possible, and should include practical aspects, especially concerning outpatient care.

Our Laparoscopic Surgical Technique and Experience in Treating Pediatric Inguinal Hernia Over the Past Decade.

BACKGROUND: Over the past decade, laparoscopic hernia repair was the most performed operation in our department. Equally, it compromises 15% of all pediatric operations performed. We aim, in this study, to review all the cases performed and extrapolate important information like reoccurrences, the incidence of metachronous inguinal hernia, complications amongst other information. MATERIAL AND METHODS: All patients under the age of 18 whom underwent elective laparoscopic hernia repair between 03/01/2007 till the 18/05/2016 were included in our study. We recorded important clinical features and studied their post-operative follow up. Equally reoccurrences, the incidence of metachronous inguinal hernia, complications and other parameters were recorded and studied. RESULTS: A total of 916 patients were operated on during the defined study period. There was a 0.17% reoccurrence rate and a 0.46% incidence of metachronous inguinal hernia. Equally a contralateral patent processus vaginalis was diagnosed and closed in 17.10%. There were no postoperative complications and we had a 0% postoperative hydrocele rate. CONCLUSION: Laparoscopic hernia repair is safe and carries all the benefits of minimally invasive surgery. We recommend that it is offered to patients and would like to refute previously claimed reports that it carries a higher reoccurrence rate or takes a long time to perform. Our reoccurrence rate of 0.17% is actually lower than many published reoccurrence rates after open repair.

Thoracoscopic Rib Resection in Children.

OBJECTIVE: The authors present a multicenter retrospective series of different benign rib lesions in children operated on using thoracoscopy. MATERIALS AND METHODS: Between 2005 and 2015, 17 rib resections were performed thoracoscopically, in four French departments of pediatric surgery. Of these 17 cases, 13 exostoses, 2 endochondromas, 1 synostosis, and 1 Cyriax's syndrome were noted. Inclusion criteria were benign tumors or rib anomalies such as synostosis, in children younger than the age of 18 years, and thoracoscopy. Open surgery and malignant tumors were excluded. Thoracoscopy was put forward using one optical port as well as one or two operative ports. RESULTS: Ten patients presented with chest pain, dyspnea, or unexplained cough. Six tumors were incidentally diagnosed. One patient presented with a chest wall deformation. Single-lung ventilation was required in 2 cases. In 1 case of endochondroma, a segmental rib resection was performed, leaving a part of the periosteum and the intercostal vessels and nerve. In this case, rib resection was performed using an endoscopic shaver drill system. As for the other cases, a simple resection of the tumor or of the bridge between two ribs (synostosis) was performed. In these cases, a Codman Kerrison laminectomy rongeur was used. There was no complication during or after surgery. Nevertheless, 2 years after surgery, pain did not disappear in 1 case, probably due to a definitive intercostal nerve damage. CONCLUSION: Benign rib lesions in children are rare. Thoracoscopy may be offered to reduce the functional deleterious consequences of an open surgery. It may be put forward especially in case of hereditary multiple exostoses where redo procedures may be required.

Minimally invasive management of intrahepatic type II gallbladder perforation: a case report.

Intrahepatic gallbladder perforation (GBP) is a rare medical entity, which creates a cholecystohepatic communication. We describe the case of a 70-year-old patient who presented with abdominal pain and a Niemeier type II GBP. This case report illustrates the minimally invasive management of a rare and life-threatening pathology.

The impact of Helicobacter pylori on the complications of laparoscopic sleeve gastrectomy.

Helicobacter pylori (H. pylori) is a very common bacterium present in the gastric tissue of up to 50 % of people, and the mucosal damage it causes can predispose to multiple comorbid conditions. This study aims to observe the prevalence of H. pylori infection in patients undergoing laparoscopic sleeve gastrectomy (LSG) and its correlation with postoperative complications. A retrospective study was done on the gastric pathology specimen results of 682 patients who underwent LSG at Amiri Hospital from 2008 to 2012. Symptomatic patients had preoperative upper gastrointestinal endoscopies (UGIEs) based on the decision of the treating surgeon, along with campylobacter-like organism test (CLO test) for H. pylori detection. The intraoperatively excised gastric specimen was sent for histopathological assessment of H. pylori, and the patients were followed up for complications. Of the 682 patients, 629 (92.2 %) were found to be H. pylori negative intraoperatively, while 53 (7.8 %) were positive. A total of 32 (4.7 %) patients were found to have postoperative complications, of which 2 (6.3 %) had H. pylori intraoperatively. No statistical significance (p = 0.71), however, was seen between the overall complication rate and H. pylori. Specifically, there were five (0.7 %) cases of leak and eight (1.2 %) cases of neuropathy, both of which were not significantly associated with H. pylori (p = 0.33 and p = 0.12, respectively). All the other complications had no evidence of H. pylori. There appears to be no association between H. pylori infection and post-LSG complications.

Routine trans-abdominal ultrasonography before laparoscopic sleeve gastrectomy: the findings.

Although some bariatric guidelines reserve pre-operative trans-abdominal ultrasonography screening for symptomatic patients and those with elevated liver enzymes, there has yet to exist a general consensus regarding this issue. Some centers still employ its use as a vital step in the workup of the bariatric patient. This study aims to observe the prevalent findings on routine pre-operative trans-abdominal ultrasonography when used as a screening tool prior to laparoscopic sleeve gastrectomy (LSG). All patients undergoing LSG were screened pre-operatively with trans-abdominal ultrasonography. A retrospective study was done of the pre-operative ultrasonography results of patients who underwent LSG at Amiri Hospital from 2008 to 2012. A total of 747 patients were included in the study, with a median age of 36 (15-68). Five hundred ninety (79.0 %) patients were females while 157 (21.0 %) were males, with an overall median body mass index (BMI) of 45 (30-90). Two hundred forty patients (32.1 %) had normal pre-operative ultrasonography results, 83 (11.1 %) were found to have gallstones, 427 (57.2 %) had fatty liver, and 55 (7.4 %) had other pathologies. There was no statistically significant association between BMI and gallstones (p = 0.545) and BMI and fatty liver (p = 0.418). Trans-abdominal ultrasonography screening prior to LSG revealed a wide range of findings but does not add significant information to the pre-operative workup of patients undergoing the procedure and should be reserved for indicated patients.
