Transient minimal hydronephrosis on contralateral kidney in infants with unilateral hydronephrosis: Is it an early sign of worsening of the affected kidney?

Background/aim: The criteria for surgical management of ureteropelvic junction obstruction are not well-defined, and there is a risk for loss of renal function before the operation. In this context, certain changes in contralateral kidney had been investigated in order to increase the sensitivity of diagnosis. In this study, we aimed to investigate whether contralateral transient minimal hydronephrosis (CTMH) can be considered as an “early alarm” sign for worsening of the affected kidney in infants with hydronephrosis.

Transition to adulthood with a bladder augmentation: histopathologic concerns.

Aim: To investigate the histopathologic changes in native bladder and gastrointestinal segment, the relation between histopathologic changes, type of operation and the period passed over operation in patients with bladder augmentation.

Materials And Methods: Twenty consecutive patients were enrolled in this study. Histopathologic evaluation of the cystoscopic mucosal biopsies from native bladder and enteric augment was performed in all patients.

Testis sparing surgery for Leydig cell pathologies in children.

Objective: The aim was to analyze testis-sparing surgical procedures in boys with Leydig cell pathologies.

Study Design: The hospital records of four boys with Leydig cell hyperplasia who underwent testis-sparing surgery for testicular masses between 2000 and 2012 were analyzed retrospectively. Tumor markers were evaluated and all boys underwent scrotal ultrasonography preoperatively.

Results of a Two-stage Technique for Treatment of Proximal Hypospadias with Severe Curvature: Creation of a Urethral Plate Using a Vascularized Preputial Island Flap.

Purpose: To present the results of a two-stage technique used for the treatment of proximal hypospadias with severe curvature.

Materials And Methods: The medical records of children with proximal hypospadias and severe curvature were retrospectively analyzed. A 2-stage procedure was performed in 30 children.

Transvesicoscopic cross-trigonal ureteroneocystostomy in children: a single-center experience.

Purpose: To evaluate the safety and efficacy of transvesicoscopic ureteric reimplantation in children.

Patients And Methods: Seventeen ureteric units in 11 patients underwent a transvesicoscopic 'Cohen' ureteroneocystostomy in 2003-2007 and the results were retrospectively analyzed. There were four boys and seven girls.

Emotional effects of hypospadias surgery on Turkish boys.

Purpose: The aim of this study is to investigate in Turkish boys the emotional effects of hypospadias repair before and after the optimal age for repair.

Materials And Methods: Forty hypospadias patients treated in our department were included in this study. Group 1 consisted of 13 patients operated on at less than 30 months of age.

Histological evaluation of the testicular nubbins in patients with nonpalpable testis: assessment of etiology and surgical approach.

There is a controversy in the literature whether testicular nubbins carry malignancy risk and excision of the nubbin is necessary in patients with nonpalpable testis. It is also controversial whether vanishing testis has the same etiopathogenesis and risk with true undescended testis. The aim of this study is to investigate the histological findings of testicular nubbins in patients with nonpalpable testis and to question etiology and surgical indications for vanishing testis.

A therapeutic method for failed bladder augmentation in children: re-augmentation.

Objective: To investigate the causes leading to the deterioration of previously successful bladder augmentation and to evaluate the efficacy of re-augmentation.

Patients And Methods: Between 1988 and 2004, 136 bladder augmentations were performed in two paediatric urological units in Hungary and Turkey. Re-augmentation was necessary in two patients after colocystoplasty and in three after gastrocystoplasty.

Preliminary report on the International Conference for the Development of Standards for the Treatment of Anorectal Malformations.

Background: Anorectal malformations (ARM) are common congenital anomalies seen throughout the world. Comparison of outcome data has been hindered because of confusion related to classification and assessment systems.

Methods: The goals of the Krinkenbeck Conference on ARM was to develop standards for an International Classification of ARM based on a modification of fistula type and adding rare and regional variants, and design a system for comparable follow up studies.

Quo vadis? Ureteric reimplantation or ignoring reflux during augmentation cystoplasty.

Objective: To decide whether antireflux surgery should be used in the presence of vesico-ureteric reflux (VUR) in children, in whom an augmentation procedure is needed, because secondary VUR in children with a neurogenic bladder, infravesical obstruction and primary VUR in the exstrophy-epispadias complex is expected to resolve after augmentation, which decreases the intravesical pressure and increases capacity.

Patients And Methods: Between 1987 and 2001, the bladder was augmented in 38 children, using no antireflux surgery in group 1 (15 patients) and antireflux surgery in group 2 (23 patients).

Results: VUR was detected in all patients on cysto-urethrography before surgery; reflux resolved after augmentation cystoplasty in 97% and 93% of refluxing units in groups 1 and 2, respectively.
