Posterior urethral valves (PUV) account for a sizeable proportion of children with chronic renal failure. Several criteria have been identified as predictive of future renal function in children with PUV. We compared the presenting features and initial treatment in two groups of Saudi children treated for PUV, with the aim of identifying any factors that might account for the differences observed in their renal function. One group (group A, 19 patients) had a serum creatinine of 80 micromol/l or less at follow-up and the other (group B, 13 patients) had higher levels. There was no significant difference in age or weight at presentation, incidence and severity of reflux, urinary tract infection, or type of primary treatment (valve ablation versus vesicostomy) between the two groups. However, after 5-7 days of catheter drainage, the mean serum creatinine level was 88+/-62 micromol/l for patients in group A compared with 172+/-77 micromol/l for those in group B (P<0.0001). This difference was highly significant. Linear regression analysis of post-drainage creatinine and serum creatinine at last follow-up showed a correlation coefficient of 0.7171 (P<0.0001). Hence the serum creatinine level after catheter drainage correlated strongly with renal function during short-term follow-up of Saudi children with PUV. This might help in the selection of the optimal initial therapy and provide some basis for prognostication.
AimWe report a case of intravesical polyvinyl-coated electric wire in the urinary bladder.Case reportA 34-year-old man presented in our clinic with irritative lower urinary tract symptoms. Three weeks earlier he had seen and felt a wire in his urethra of which he was unaware of the origin. Radiologic evaluation revealed an electric wire completely coiled up in the urinary bladder. It was removed through a suprapubic cystotomy.DiscussionPatients are usually too ashamed to admit the cause of an intravesical foreign body, which is often sexual or erotic in origin. Radiologic evaluation usually reveals the nature and size of the foreign body in the bladder of patients evaluated for recurrent urinary tract infection. Open surgery or an endoscopic approach may be used for their extraction.
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.
