BackgroundPyeloplasty for ureteropelvic junction obstruction correction is a common procedure, but the optimal method for protective diversion after pyeloplasty is still a matter of debate.ObjectivesHere, we present our clinical trial experience using a single percutaneous externalized nephroureteral (NU) 5-Fr catheter (infant feeding tube) with multiple side holes as the sole instrument of drainage to provide a protective mechanism.Materials and MethodsIn this prospective study, we analyzed the charts of 142 patients who underwent pyeloplasty from August 2001 through October 2008. We used a single externalized NU 5-Fr catheter with multiple side holes for postoperative upper tract diversion. The catheter was removed in the office after 10 - 14 days. Complications from the use of this catheter, including poor catheter function, premature dislodgement, urinary tract infection, leakage, urinoma, and anastomotic stenosis, were evaluated. The operations were performed by two surgeons at two separate centers.ResultsIn all, 148 pyeloplasty procedures were performed on 142 patients. The mean hospital stay length was 2 (1 - 3) days. A contrast study through a catheter demonstrated excellent drainage with no leakage in all patients. Immediately after catheter removal, febrile urinary tract infection and transient obstructive symptoms and signs occurred in 15 patients.ConclusionsUsing a percutaneous externalized NU 5-Fr catheter was sufficient as a protective measure after open pyeloplasty. It costs less than other diverting systems, such as DJ, and can be removed in the office. Therefore, it can be a safe and cost effective procedure, especially in developing countries where cystoscopic set ups are not readily available. There were only a few notable complications.
Objectives: Reconstruction of ventral penile skin, in midshaft and distal hypospadias is problematic in many cases of severe ventral dysplasia. So we plan to use the tailored preputial skin island flap (PSIF) to cover the ventral defect. Methods: In this prospective cohort study 224 boys with midshaft and distal hypospadias associated with sever ventral dysplasia were operated from March 2009 until January 2016. The large U-shaped bare area which exposed on the ventrum after release of curvature was quilted by the PSIF as a patch. In each case, the variable size of the flap was required. The prepuces without the predominant artery were excluded from the study due to poor vasculature. The patients followed for 8 months to 7years. Results: Flap ischemia developed in 7 initial cases (3.125%), all of which subsequently faded. Some degree of ischemic discoloration was encountered at margins of the flap (12 cases, 5.3%), which resolved spontaneously. In 5 out of 224 patients (2.23 %), the flap persisted as a hypertrophied area of skin in the long-term follow-up. All of them needed to be corrected surgically. Near normal appearing penile skin was accomplished in the majority of patients during the follow-up. However, lack of the median raphe in the ventrum was evident in all. Conclusions: Tailored preputial skin island flap, as a native tissue to cover the exposed large bare area on the ventrum in cases of the distal and mid hypospadias with severe ventral dysplasia may improve the appearance and adequacy of the penile skin. It provides room for full erection and improves the patient’ s perception of body image and self-esteem.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
