A Single Center Experience of Special Cases: Isolated Adrenal Myelolipoma and Adrenocortical Adenoma with Myelolipomatous Component.

Objective: Isolated adrenal myelolipoma (IAM) is an uncommon, nonfunctioning tumour of the adrenal gland, primarily composed of adipose tissue and hematopoietic trilinear cells. The etiopathogenesis and clinical relevance of this neoplasm remain poorly understood. However, similar myelolipomatous alterations can also occur within adrenocortical adenomas.

Relation between Cajal Cell Density and Radiological and Scintigraphic Outcomes in Patients with Ureteropelvic Junction Obstruction.

Introduction: In this study, we aimed to investigate the correlation between Cajal cell density and preoperative and postoperative radiological and scintigraphic parameters in ureteropelvic junction obstruction (UPJO).

Methods: The study group consisted of 41 renal units (38 consecutive patients; 13 female and 25 male) surgically treated for UPJO. UPJ specimens from patients were immuno-stained with CD117 (c-kit) antibody for interstitial Cajal cells (ICCs).

Protein expression in vesicoureteral reflux: What about children?

Purpose: Pathogenesis of vesicoureteral reflux (VUR) which concerns improper embryonal ureteric bud development still remains controversial, despite current studies have revealed several candidate genes. In this study, we aimed to determine the protein expression of certain genes which might play role in the pathogenesis of VUR, in the resected ureterovesical junction segments.

Methods: The study group consisted of 19 children; 12(63%) girls, 7(37%) boys who had ureteroneocystostomy (UNC) operation; 3(15.

Comparison of corporal plication for the correction of congenital penile curvature in pre-pubertal and post-pubertal patients: Does age matter?

We retrospectively reviewed and compared the results of corporal plication procedures for the correction of congenital penile curvature (CPC) between pre-pubertal and post-pubertal boys and find whether age matters in the success rates. We reviewed the records of 32 patients with CPC without hypospadias treated by simple plication near the 12 o'clock position between 1998 and 2018 in our clinic. Patients under 13 years of age and not had puberty yet were accepted as pre-pubertal.

Did our current initial treatment practice change after EAU/ESPU vesicoureteral reflux risk grouping?

Background/purpose: The "European Association of Urology (EAU) Guidelines on Vesicoureteral Reflux (VUR) in Children (September 2012)" established risk classification by analyzing and defining risk factors for each patient. In this study we aimed to investigate how our initial treatment procedures were affected by EAU/ESPU guideline vesicoureteral reflux risk grouping and to compare the early clinical results of treatments performed before and after the risk classification in our patients with VUR.

Materials And Methods: 334 renal units with regular clinical follow-up who were treated owing to VUR (vesicoureteral reflux) between years 2009 and 2017 were retrospectively reviewed.

Factors Affecting the Success Rate of Percutaneous Nephrolithotomy in Paediatric Patients.

In this study, we aimed to determine factors affecting the success rate of percutaneous nephrolithotomy (PNL) in children. The series consisted of 41 consecutive children operated on by the same surgical team for renal calculi with PNL between June 2002 and May 2015 in our institution. A single calyx or pelvic stone was described as simple, while calculi located in more than one location (calyx and pelvis or more than one calices) or staghorn stones were described as complex.

Changes in Cajal cell density in ureteropelvic junction obstruction in children.

Introduction: Congenital ureteropelvic junction obstruction is one the most common causes of neonatal hydronephrosis. The etiology of the ureteropelvic junction (UPJ) obstruction has not been clearly established. The presence of a hypoplastic, adynamic ureteral segment is thought to be the major cause of an UPJ obstruction.

Urodynamic disorders and renal scarring in pediatric patients with nonmonosymptomatic nocturnal enuresis.

Background/aim: In nonmonosymptomatic nocturnal enuresis (NMNE), the incidence of organic abnormality and urodynamic disorder is more frequent than the general population. The aim of this study is to identify urodynamic disorders and renal scarring in children with NMNE.

Materials And Methods: This study evaluated the urodynamic disorders and renal scarring of a total of 30 patients who were diagnosed with NMNE.

Factors affecting complication rates of ureteroscopic lithotripsy in children: results of multi-institutional retrospective analysis by Pediatric Stone Disease Study Group of Turkish Pediatric Urology Society.

Purpose: We evaluated factors affecting complication rates of ureteroscopy for pediatric ureteral calculi.

Materials And Methods: We retrospectively evaluated 642 children who underwent ureteroscopy at 16 Turkish centers between 2000 and 2010. Semirigid ureteroscopy was used with various calibers to treat 670 ureteral units in 660 sessions.

Repair of hypospadiac urethral duplication with dismembered urethroplasty.

Urethral duplication is a complex and rarely seen anomaly with three anatomic variants: epispadiac (dorsal), hypospadiac (ventral) and Y-type. Here we report an 11-year-old male patient with hypospadiac urethral duplication who presented with daytime urinary incontinence and dribbling, urethral stricture and possible obstructive uropathy. After endoscopic treatment of the stricture in the ventral (dominant) urethra, urethral reconstruction was done anastomosing the ventral (dominant) and dorsal (non-dominant atretic urethra) in a dismembered fashion.

Vincristine-induced peripheral neuropathy and urinary bladder paralysis in a child with rhabdomyosarcoma.

Vincristine commonly induces peripheral neuropathy but rarely causes voiding dysfunction. In this report, we describe a case of neurogenic bladder and peripheral neuropathy caused by the neurotoxic effect of vincristine and documented by urodynamic testing and electromyography. Neurologic evaluation aided in monitoring and understanding this problem.

Bladder augmentation: Review of the literature and recent advances.

Bladder augmentation is an important tool in the management of children requiring reconstructions for urinary incontinence or preserving of the upper urinary tract in congenital malformations. We reviewed the literature and evaluated the long-term results of enterocystoplasty in the pediatric age group and summarized techniques, experimental options and future perspectives for the treatment of these patients. For this purpose, a directed Medline literature review for the assessment of enterocystoplasty was performed.

The impact of pelvicaliceal features on problematic lower pole stone clearance in different age groups.

Aim: Our aim was to evaluate the impact of pelvicaliceal variables in pediatric and adult age groups who underwent SWL for lower caliceal calculi.

Methods: 25 pediatric and 78 adult patients treated with extracorporeal shock wave lithotripsy (SWL) between 1996 and 2004 were enrolled into the study after exclusion of patients with hydronephrosis, major renal anatomic anomalies, non-calcium stones, history of recurrent stone disease and previous renal surgery. Lower pole infundibulopelvic angle (IPA), infundibular length (IL), infundibular width (IW) and pelvicaliceal volume were measured from pre-SWL intravenous urography.

Assessment of urinary symptoms in children with dysfunctional elimination syndrome.

Objective: This study was organized to form a symptom scale for diagnosis and assessment of urinary and bowel symptoms in children with dysfunctional elimination syndrome (DES).

Methods: The study group included 81 children presented to our clinic with symptoms of DES like enuresis, abnormal voiding, urinary tract infection and urgency, between January 2003 and February 2004. Age matched 102 children with no history of urological complaints were randomly recruited from a public school as control group.

Evaluation of sexual function in women with overactive bladder syndrome.

Introduction: Of late, little data is available concerning factors affecting female sexual function. In the present study, we evaluated the effects of overactive bladder (OAB) syndrome symptoms on female sexual function.

Materials And Methods: 40 patients with OAB symptoms and 40 age-matched women as a control group were evaluated using the Female Sexual Function Index (FSFI) for sexual function.

The impact of urinary incontinence on female sexual function.

Although urinary incontinence is not a life-threatening disorder, it has been shown to have detrimental effects on quality of life in terms of psychological, social, and sexual problems. In this study, investigators explored the effects of different types of urinary incontinence on female sexual function with a reliable and validated questionnaire, the Female Sexual Function Index (FSFI). One hundred fifty-three women with complaints of incontinence were enrolled in the study.

Minimally invasive treatment of ureteral calculi in children.

A retrospective analysis was done to determine the efficacy of shock wave lithotripsy (SWL) and ureteroscopy in the treatment of paediatric ureteral calculi. We reviewed the records of 67 (35 boys, 32 girls) children (71 ureters) admitted to our clinic for treatment of ureteral calculi during 1990-2005. The initial treatment method was SWL in 80.

Parameatal cyst of urethra: a rare congenital anomaly.

We report a case of parameatal urethral cyst in a 15-year-old boy which is a very rare congenital anomaly. The cyst recognized at infancy but the boy presented to our clinic at the age of 15 when the mass was grown enough to cause spraying of urine and poor cosmesis. Complete excision of the cyst with total removal of the epithelium is the required for treatment and prevention of recurrence.

Prolapse of a simple ureterocele presenting as a vulval mass in a woman.

A 48-year-old woman presented with a large vulval mass after prolapse of a ureterocele. Her past excretory urogram showed a filling defect (cobra head appearance) in the bladder related to a single-system ureterocele on the left. The mass was manually reduced back through to the urethra under sedation and a urethral catheter was inserted.

Factors affecting the success rate of extracorporeal shock wave lithotripsy for renal calculi in children.

The aim of the study was to analyse factors affecting the success rate of extracorporeal shock wave lithotripsy (ESWL) in children with renal calculi. We performed a retrospective analysis reviewing records of 85 (40 female, 45 male) children (89 renal units) subjected to ESWL for treatment of renal calculi during 1990-2005 in our department. As 4 patients had bilateral calculi and 19 children (21 renal units) had renal stones at more than one different site, each location was analysed separately for convenience.

Pelvicaliceal anatomical variation between stone bearing and normal contralateral kidneys--does it have an impact on stone formation in pediatric patients with a solitary lower caliceal stone?

Purpose: We aimed to investigate the probable effect of pelvicaliceal anatomical differences between stone bearing and normal contralateral kidneys on the etiology of stone formation in children with a solitary lower pole caliceal stone.

Materials And Methods: We reviewed the clinical records of 25 pediatric patients who underwent SWL for a solitary lower caliceal stone and 15 healthy pediatric patients who served as controls. Lower pole IPA, IL and IW, together with other caliceal variables obtained from the pelvicaliceal anatomy of the stone bearing and contralateral normal kidneys of patients with urolithiasis, and both kidneys of the control group were measured based on excretory urography.

Extracorporeal shock wave lithotripsy in L-shaped kidneys: report of two cases.

The L-shaped or tandem kidney is a type of crossed ectopia with fusion in which the crossed kidney assumes a transverse position during its attachment to the inferior pole of the other kidney. Calculus formation is a well-known sequel of congenital abnormalities of the urinary tract and we like to present two patients harbouring calculi in L-shaped kidneys treated by extracorporeal shock wave lithotripsy (ESWL). The first patient had a calculus in renal pelvis of the transverse kidney.
