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.

Efficacy of tolterodine in children with overactive bladder.

Aim: Tolterodine is an anticholinergic drug used for the treatment of overactive bladder. We evaluated the effects of tolterodine on clinical symptoms and compared its efficacy with that of oxybutynin in terms of bladder capacity, bladder wall thickness, and post-void residual volume in children with overactive bladder.

Material And Methods: Twenty-six patients who were treated with tolterodine for overactive bladder (20 girls, mean age 8.

A Novel Mutation of AMHR2 In Two Siblings with Persistent Müllerian Duct Syndrome.

Persistent müllerian duct syndrome (PMDS) is characterized by the presence of müllerian duct derivatives in otherwise phenotypically normal males. It is caused in approximately 85% of the cases by mutations in the AMH gene or its type II receptor (AMHR2). We report on 2 brothers with normal external genitalia but high serum AMH levels.

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.

Ultrasound-Guided Percutaneous Nephrostomy Performed on Neonates and Infants Using a "14-4" (Trocar and Cannula) Technique.

Purpose: Percutaneous nephrostomy (PCN) catheters are placed under combined ultrasound and fluoroscopic guidance in the interventional radiology suite and present unique challenges in neonates and infants. The purpose of this study was to demonstrate feasibility of PCN using a "14-4" (trocar and cannula) technique on neonates and infants.

Materials And Methods: Between September 2009 and June 2014, data for 27 kidneys from consecutive 22 neonates or infants who underwent PCN catheter placement using the "14-4" technique were retrospectively analyzed.

A Translocation Renal Cell Carcinoma with Skeletal Muscle Metastasis in a Child.

Renal cell carcinoma is a tumor that is well known for a high rate of metastasis to several locations like the lung, liver and bones. Skeletal muscle is a rare location for dissemination of the disease. Herein, we describe a 7-year-old boy who presented with flank pain.

Subserosal leiomyoma of uterus mimicking an ovarian tumor in adolescent patient.

Uterine leiomyomas are the most common gynecological tumors in adult women. These benign tumors are rarely seen in the adolescent population: there are only a few cases that have been reported so far in this age group. In this case report, we present a giant uterine leiomyoma that mimicked an ovarian tumor in a 15-year-old girl.

Ovary-sparing surgery for teratomas in children.

Aim: To share our experience in ovary-sparing surgery for teratomas in children.

Patients And Methods: The medical records of nine patients (mean age of 11.2 years, r 6-15 years) who had undergone ovary-sparing surgery for teratoma were analyzed retrospectively.

Rare cause of dysuria: eosinophilic cystitis.

Eosinophilic cystitis is an inflammatory condition characterized by eosinophilic infiltration of whole layers of the bladder wall. The condition occurs more commonly in adults. We report a case of eosinophilic cystitis mimicking a bladder tumor in a 5-year-old boy with symptoms of dysuria and urinary incontinence.

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.

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.

Purpose: We review our experience of treating intestinal rotation anomalies in infants and children in the 22-year period between 1978 and 2000.

Methods: The type of operation performed, postoperative complications, and mortality were compared in three age groups. Group 1 consisted of neonates <1 month old, Group 2 consisted of infants aged <1 year old, and Group 3 consisted of children aged >1 year old.

Management of portal hypertension in children: a retrospective study with long-term follow-up.

Objectives: Data regarding the management of the portal hypertensive haemorrhage in the paediatric patients have yielded conflicting results. The purpose of this study was to evaluate the efficacy of beta-blocker (propranolol) alone, sclerotherapy alone and beta-blocker + sclerotherapy combination in the management of portal hypertension in the paediatric population.

Methods: Medical information was retrieved from the records of 62 children with portal hypertension who were under treatment during at least two years of follow-up period.

Is it possible to create a slit-like meatus without incising the urethral plate?

A series of hypospadias repairs using the Mathieu and V-incision-sutured (MAVIS) technique, aiming to achieve a normal-looking,vertical, slit-like meatus in 32 patients was reviewed. A Mathieu procedure was performed in 26 patients as a primary repair and in 3 as a rescue operation. In another 3 patients who had severe proximal hypospadias with failed repair, techniques other than Mathieu's were used.

Arterial carbon dioxide markedly increases during diagnostic laparoscopy in portal hypertensive children.

Unlabelled: Several factors are responsible for hypercarbia during laparoscopic procedures. This study was undertaken because we observed a sudden increase in PaCO(2) in children with portal hypertension (PHT), which was unusual in healthy children undergoing laparoscopic procedures. Fifty-seven children underwent laparoscopic procedures under general anesthesia and were mechanically ventilated.

Esophageal variceal bleeding secondary to portal hypertension: endoscopic sclerotherapy as the first-step treatment.
