PURPOSE: Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) syndrome is a rare syndrome characterized by Müllerian duct and renal anomalies. It is usually regarded as a disease of adolescence; however, due to a number of possible problems, the management of patients before puberty should not be overlooked. We assessed the clinical course of prepubertal patients to propose appropriate management. MATERIALS AND METHODS: We retrospectively assessed 43 prepubertal OHVIRA syndrome patients who were diagnosed and followed up at our institution from July 2004 to June 2015...

Ectopic ureteroceles are one of the most common human urinary tract anomalies. They tend to be recognized and treated in early childhood, especially when they have prolapsed. In most cases surgical therapy is inevitable. In this case report, however, we present the unusual case of a 26-year-old woman suffering from a prolapsed cecoureterocele without any known history of an ectopic ureterocele so far. She was successfully treated without the need for a surgical procedure.

INTRODUCTION: Symptomatic pediatric ureterocele has diverse manifestations, making evidence-based management impractical. Thus, detailed visualization of ureterocele anatomy prior to first surgical incision is invaluable. Retrograde ureterocelogram (RUC) is a simple, underutilized radiologic technique that can be performed during cystoscopy. This study sought to determine whether RUC changes surgical management by more accurately depicting the complex ureteral and ureterocele anatomy, compared with renal ultrasound (US) and voiding cystourethrography (VCUG)...

AIM: To evaluate the success of endoscopic deroofing with double J (DJ) stenting as a primary treatment modality of uncomplicated ureterocele. PATIENTS AND METHODS: All babies with uncomplicated ureterocele referred to us between 2005 and 2015 were to be prospectively recruited into the study without any exception. The preoperative management would include ultrasound KUB on a fixed protocol, micturating cystourethrogram, DTPA scan and MRU (magnetic resonance urography) or IVP (intravenous pyelography)...

Prenatal ultrasound detection of fetal ureterocele with bilateral hydro-ureteronephrosis, obstruction of the bladder outlet and progressive amniotic fluid reduction can be associated with a significant risk of end-stage chronic renal disease after birth. Fetal cystoscopic laser incision of the ureterocele, with the aim of relieving the bladder outflow obstruction to preserve renal function, has been previously reported in one case, with a favourable outcome. This report employed standard 3.5-mm fetoscopic access to the amniotic cavity and the fetal bladder...

INTRODUCTION: Although cross-trigonal ureteral reimplantation (Cohen) is a commonly used technique in children, it represents a non-physiological transfer of the ureteral orifices and may prove challenging with regard to endoscopic ureteral operations in later life. In 1964, Mathisen described an alternative method of ureteral reimplantation with lateralization of the neohiatus, creating an orthotopic course of the submucosal ureter. We have evaluated success and complication rates of both techniques that were applied sequentially at our departments...

BACKGROUND: Retroperitoneoscopic upper pole heminephrectomy (RUHN) in duplex kidney in children remains a challenging procedure with a need for postoperative functional assessment of the remnant lower pole. We aimed to calculate the incidence of long-term functional renal outcomes in these children and examine the effect of age on those outcomes. METHODS: A multicenter retrospective cohort study of 9 years included all patients undergoing RUHN and evaluated by renal ultrasound (US) and dimercaptosuccinic acid (DMSA) scintigraphy pre and postoperatively...

Ectopic ureter and ureterocele are rare congenital anomalies. As such, are seldom encountered incidentally during urologic surgery. We present a case illustrating an unforeseen encounter of an ectopic ureter with an associated ureterocele during a robotic assisted laparoscopic prostatectomy (RALP) and the surgical technique used to adapt to the anatomical variation.

Ureterocele is a common ureteric anomaly detected in pediatric population. Ureterocele diagnosis and evaluation need a variety of radiological methods. We report a case of 5-year-old female child sent for (99m)Tc-diethylene triamine pentaacetic acid scan for evaluation of glomerular filtration rate and excretory function of kidneys in view of right-sided hydroureteronephrosis and pyonephrosis with percutaneous tube in situ. Incidental photopenia was noted in the urinary bladder. On ultrasonography of abdomen cause of this photopenia was found to be an intravesical ureterocele...

A cecoureterocele is a rare form of ectopic ureterocele that the orifice of the affected ureter is within the bladder, but the cavity of the ureterocele extends beyond the bladder neck into the urethra. We present a case of a newborn boy with a large cecoureterocele with contralateral renal rupture. He required an emergency transurethral incision of the ureterocele for the treatment of acute renal failure and respiratory disorder.

Congenital anomalies of the kidney and urinary tract (CAKUT) form a group of heterogeneous disorders that affect the kidneys, ureters and bladder, with frequent asynchronous presentations and multiple CAKUT associations in the same individual. Urinary tract formation is a complex process, dependent of the interaction of multiple genes and their sub-product. The same genic alterations can lead to different molecular expressions and different morphological anomalies. The ureterocele is a cystic dilation of the distal intramural ureter, resulting in obstruction of urine flow, dilation of the ureter and renal pelvis and loss of renal function...

It is very uncommon for urothelial carcinoma to develop in an ureterocele. It is generally discovered in an imaging study or in connection with haematuria. We found very few reports in the literature. Here, we report on the case of a 71-year-old male who initially presented with haematuria and low back pain and who then underwent transurethral resection for an intraureterocele tumour. Pathology confirmed urothelial carcinoma.

OBJECTIVE: To evaluate the performance of transvesical laparoscopic surgery for patients with complete double pelvis and ureter. METHODS: A total of 10 patients were included in the present study: five had complete double pelvis and ureter with ureterocele (group A), and five did not have ureterocele (group B). Three small incisions of 5 mm were used, without incision in the lower abdomen. In group A patients, the ureterocele wall was resected, and two ureters were sufficiently detached as a combined ureteral complex...

OBJECTIVE: To discuss the clinical classification and treatment protocols of complete duplication of kidney and ureter in children. METHODS: Between March 2000 and February 2015, 106 children with complete duplication of kidney and ureter were treated, and the clinical data were retrospectively analyzed. Of them, there were 11 boys and 95 girls, aged from 1 month to 11 years (mean, 3.5 years); one side was involved in 88 cases and two sides in 18 cases. They were divided into 4 types according to image examinations and clinical presentations: 14 patients who needed no special treatment were classified into the first type, 15 patients who underwent reconstruction into the second type, 74 patients who underwent segment removal of renal dysplasia and subtotal excision of abnormal duplicated ureter into the third type, and 3 patients who underwent removal of the whole affected kidney and subtotal excision of whole ureter into the forth type...

Zinner syndrome, the association of congenital seminal vesicle cyst and ipsilateral renal agenesis, is more often reported in adults or older adolescents. We present a case of a boy, followed up in our hospital since birth for right renal agenesis who at the age of 4 years presented a right paravesical cyst on ultrasound. The cyst was initially considered as an ureterocele. The diagnosis of Zinner syndrome was made later, at the age of 15 years by ultrasound and magnetic resonance imaging; at that moment the cyst had increased in size and had changed in aspect...
