Nonischemic Priapism in Childhood: A Case Series and Review of Literature.

Introduction:  Nonischemic priapism (NIP) in childhood is a very rare affection. In the literature, patients with NIP are described mainly incidental after perineal trauma. Many of them underwent embolization of either internal pudendal artery or bulbocavernosal arteries.

Pyeloplasty in children: is there a difference in patients with or without crossing lower pole vessel?

Introduction: Most of the children with hydronephrosis do not require any surgical intervention. However, in individual cases, irreversible loss of renal function can develop. Predictive criteria have been proven ineffective so far in determining in which children obstruction will lead to renal damage.

Inflammatory tumour of the prostate in a 4-year-old boy.

An inflammatory tumour of the prostate is very rare in young boys without genital anomalies. We report a 4.5-year-old boy presenting with pollakisuria, dysuria, secondary urinary incontinence and decreased urine stream.

Redo-endorectal pull through following various pull through procedures in Hirschsprung's disease.

Background: The purpose of this study was to analyse the outcome of redo-endorectal pull through in Hirschsprung's disease following different original pull through procedures. In the past, redo-endorectal pull through was mainly performed following endorectal pull through, but not following the Duhamel procedure. We present the outcome of eight patients after redo-endorectal pull through, including five who underwent Duhamel pull through as original procedure.

Contrast-enhanced dynamic MR nephrography using the TurboFLASH navigator-gating technique in children.

The purpose of this work was to test the feasibility of an MR examination protocol for the comprehensive assessment of renal morphology, excretion and split renal function using a navigator-gated TurboFLASH sequence. A navigator-gated T1-weighted single-slice TurboFLASH sequence suitable for dynamic MR urography and nephrography was implemented. A protocol was developed allowing for assessment of urinary excretion and split renal function by recording the renal clearance of a gadolinium (Gd) diethylene-triamine-pentacetic-acid (DTPA) bolus.

Renal dysplasia in children with posterior urethral valves: a primary or secondary malformation?

Routine prenatal ultrasound examination of the urogenital tract is of importance in patients with posterior urethral valves (PUV), because the renal function and long-term prognosis of these patients depend on early diagnosis and subsequent therapy. Opinion is divided as to whether the often-observed association of PUV with renal dysplasia represents a primary malformation or a secondary pathology caused by recurrent infections. These aspects should have an influence on therapeutic consequences and optimal timing of therapy in order to preserve long-term renal function.
