Purpose: To compare surgical scars assessed by a validated patient reported outcome questionnaire in children undergoing open (OP), laparoscopic (LP), or robotic-assisted (RALP) pyeloplasty. Secondary aim was to assess the influence on the outcomes of variables such as gender or body mass index (BMI). Materials and methods: Observational, cross-sectional, multicentric study of patients undergoing primary pyeloplasty between age 10- and 18-year at 5 tertiary Italian institutions in the period 01/2010 to 12/2019. Of 227 eligible patients, 114 (50%) participated. OP was performed in 37 (32%), LP in 30 (26%) and RALP in 47 (41%), After a median (IQR) follow-up of 5.2 (2.3-7.8) years, scars were measured and assessed by a validated Patient Scar Assessment Questionnaire (PSAQ). Scores were compared among techniques and in accordance to several variables. Results: The median length of the surgical scar at follow-up was significantly larger (p

The management of UCs remain controversial, especially for UCs with duplex collecting systems that still represent a great challenge in paediatric urology. Several approaches have been used and a shared management is not yet validated.Aim of our study is to evaluate the results of the endoscopic treatment of UC comparing ortothopic single-system UC and ectopic duplex-system UC over a 10-year period in a single referral tertiary center. Success was defined as resolution of dilation, lack of urinary infections and preservation of renal function.We retrospectively reviewed medical records of children with a diagnosis of UC who underwent endoscopic puncture at our division from January 2009 to January 2019. Patients were divided in two groups: Group A composed of patients with ectopic UC associated with renal duplex system and Group B with orthotopic UC in single collecting system.We identified 48 paediatric patients treated with transurethral primary endoscopic incision. Groups result homogeneous for clinical and pathological characteristics. The only statistical significative difference between the two samples was the age at diagnosis (p value with Yates correction = 0.01).We considered as a therapeutic success infections control and the elimination of obstruction with preservation of global kidney function. Based on that, our success rate after single (77%) or double (92%) endoscopic treatment is higher than data reported in literature. Differently from previous studies, vescico-ureteral reflux without UTIs was not considered as a failure of the procedure. The present study has some limitations: it is a retrospective and monocentric serie and it lacked a longer follow-up; on the other hand, it has been conducted on a quite large sample size and it is one of the few studies that compares the endoscopic treatment between orthotopic and ectopic UC.Our data report primary endoscopic puncture of ureterocele as a simple, effective, and safe procedure also in long-term follow up. This technique avoids the need for additional surgery in the majority of the patients, also in the case of an ectopic UC associated to a duplex system.

Summary Introduction Anterior urethral valves (AUV) are a rare cause of lower urinary tract obstruction which could progress to renal damage, Clinical presentation varies according with patient's age and severity of obstruction, but, in most cases, diagnosis is based on voiding cysto-urethrogram (VCUG). To date, the treatment of choice is endoscopic ablation even if approved guidelines about the overall management of AUVs, including the recognition and treatment of residual valves, are not available. Objective We describe our protocol for AUV treatment based on primary endoscopic valve ablation followed by check cystoscopy 15 days later. Study design Medical records of 5 patients with AUVs admitted from 2008 to 2018 to our Pediatric Urology Unit were retrospectively reviewed. Blood tests, urinalysis, renal US and VCUG were performed in all children, while urodynamic evaluation was performed in the 3/5 patients who could void spontaneously. All patients underwent endoscopic valves ablation and after 15 days after a second look cystoscopy was performed. Follow up was based on clinical and radiological evaluation with US, urinalysis and blood tests. Postoperative non-invasive urodynamic studies were performed in the 3/5 patient toilet-trained patients and VCUG was performed in 1/5 patient. Results and Discussion: At primary endoscopic ablation cystoscopy revealed AUVs in the penile urethra in three patients, in the penoscrotal urethra in one case, in the bulbar urethra in another case. In 3/5 patients check cystoscopy found residual valves and a second endoscopic ablation was performed. All patients achieved symptoms release and improved urodynamic parameters. No intra or post-operative complication were reported. The assessment of residual valves is variable in literature and it is usually described for posterior urethral valves (PUVs). Few series report the use of VCUG within the first week after valve ablation, our experience instead suggests that performing a second look cystoscopy, is very effective to evaluate the presence of residual AUVs and eventually proceed with further ablation. Conclusion Endoscopic ablation is the gold standard treatment for AUV, but residual valves management is not clearly defined. According to our experience, a check cystoscopy 15 days after primary ablation allows to identify and treat possible residual valves showing good results in terms of safety and efficacy.
