    Objective: To conduct a systematic review on single scrotal incision orchiopexy. Materials and Methods: A search was performed using Pubmed, through which 16 articles were selected out of a total of 133. the following conditions were considered exclusion criteria: other surgical methods such as an inguinal procedure or a laparoscopic approach, retractile testes, or patients with previous testicular or inguinal surgery.Results: A total of 1558 orchiopexy surgeries initiated with a transcrotal incision were analyzed. Patients' ages ranged between 5 months and 21 years. Thirteen studies used high scrotal incisions, and low scrotal incisions were performed in the remainder of the studies. in 55 cases (3.53%), there was a need for inguinal incision. Recurrence was observed in 9 cases, testicular atrophy in 3, testicular hypotrophy in 2, and surgical site infections in 13 cases. High efficacy rates were observed, varying between 88% and 100%.Conclusions: Single scrotal incision orchiopexy proved to be an effective technique and is associated with low rates of complications.Univ Fed Bahia, BR-41170290 Salvador, BA, BrazilUniversidade Federal de S√£o Paulo, S√£o Paulo, BrazilUniversidade Federal de S√£o Paulo, S√£o Paulo, BrazilWeb of Scienc

    The buccal mucosa fenestrated graft for Bracka first stage urethroplasty: experimental study in rabbits

    Objective To histologically evaluate, in an experimental study in rabbits, the integration process of the buccal mucosa fenestrated graft applied in the corpora cavernosa for Bracka first stage urethroplasty. Materials and Methods A urethral defect was surgically created in 16 male rabbits of the New Zealand breed through the excision of the penile urethra. The urethral defect was corrected by applying buccal mucosa fenestrated graft through two cruciform incisions in the distal portions of its longitudinal axis. The animals were sacrificed at 2, 4, 8 and 12 weeks post surgery and their genitals were subjected to clinical and histological assessment. Results The buccal mucosa fenestrated graft showed complete uptake in all groups, with keratinization squamous metaplasia and mucosal proliferation of the fenestrated areas. The fenestrated graft area represented an increase in length of 25% in length in relation to the original standard graft. Conclusions The fenestrated buccal mucosa graft presented total integration to the adjacent epithelia with re-epithelization of the incision areas of the graft (fenestrations) and no significant inflammatory or scarring reactions when compared to other mucosa transplanted areas; therefore its application is viable in cases of extensive urethral defect whenever the donating area might be insufficient.Federal University of S√£o Paulo Departament of Urology (PO, HB, AR, UBjr, VO, AMjr) Department of Pathology (RD)UNIFESP, Departament of Urology (PO, HB, AR, UBjr, VO, AMjr) Department of Pathology (RD)SciEL

    Elective appendicovesicostomy in association with monfort abdominoplasty in the treatment of prune belly syndrome

    OBJECTIVE: To evaluate the role of elective appendicovesicostomy in association with Monfort abdominoplasty to avoid urinary tract infection (UTI) and renal damage in the post-operative follow-up of patients with prune belly syndrome. MATERIALS AND METHODS: We followed 4 patients operated in our institution (UNIFESP) (Monfort, orchidopexy and Mitrofanoff) and compared them to 2 patients treated similarly, but without an appendicovesicostomy, in a second institution (UFBA). We evaluated postoperative clinical complications, UTI and preservation of renal parenchyma. Patients were followed as outpatients with urinalysis, ultrasonography (US) and occasionally with renal scintigraphy. RESULTS: Mean follow-up was 23.5 months. Immediate post-operative course was uneventful. We observed that only one patient with the Mitrofanoff channel persisted with UTI, while the 2 patients used as controls persisted with recurrent pyelonephritis (> 2 UTI year). CONCLUSION: Our data suggest that no morbidity was added by the appendicovesicostomy to immediate postoperative surgical recovery and that this procedure may have a beneficial effect in reducing postoperative UTI events and their consequences by reducing the postvoid residuals in the early abdominoplasty follow-up. However, we recognize that the series is small and only a longer follow-up with a larger number of patients will allow us to confirm our suppositions. We could not make any statistically significant assumptions regarding differences in renal preservation due to the same limitations.Federal University of S√£o Paulo Division of UrologyFederal University of Bahia Division of UrologyUNIFESP, Division of UrologySciEL

    Cross-cultural adaptation of the dysfunctional voiding score symptom (DVSS) questionnaire for Brazilian children

    PURPOSE: To translate and culturally adapt the Dysfunctional Voiding Symptom Score (DVSS), questionnaire into Brazilian Portuguese. MATERIALS AND METHODS: The 10-item Dysfunctional Voiding Symptom Score (DVSS) was translated into Brazilian Portuguese according to a standard methodology: translation, synthesis, back-translation, Expert Committee, and pre-testing. After the translation process the final version was pre-tested and patient responses were analyzed to identify necessary modifications. Reliability was evaluated using the test-retest method, and internal consistency was assessed using Cronbach’s alpha. RESULTS: The Cronbach’s alpha coefficient was calculated in the test and retest phases. Internal consistency was found to be satisfactory, as confirmed by a Cronbach’s alpha coefficient of 0.76 for the test and 0.77 for the retest. A high degree of stability was found in the test/retest, with an intraclass correlation coefficient (ICC) of 0.960 (p < 0.001; 95% CI: 0.943-0.972). CONCLUSION: The cross-cultural adaptation process of the Dysfunctional Voiding Symptom Score questionnaire to be used on Brazilian children was successfully completed following internationally accepted methodologies.Pernambuco State University Division of Pediatric UrologyFederal University of Bahia Division of Pediatric UrologyFederal University of Juiz de Fora Division of Pediatric UrologyUrology and Nephrology Institute Division of Pediatric UrologyFederal University of São Paulo Division of Pediatric UrologyHospital for Sick Children Division of Pediatric UrologyUNIFESP, Division of Pediatric UrologySciEL
