Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA), or Herlyn–Werner–Wunderlich syndrome, is a rare Müllerian duct anomaly that is characterized by a triad of uterus didelphys, unilateral obstructed vagina, and ipsilateral renal agenesis. Patients with this anomaly usually present after menarche with abdominal pain or a pelvic mass which worsens over some time. Herein, presented is a case of a 12‑year‑old nulligravid with cyclic pelvic pain and palpable pelvic mass after her menarche. A series of diagnostic tests were done which were compatible with the diagnosis of OHVIRA with an associated finding of ectopic ureteral insertion into the obstructed hemivagina and nonfunctional urinary bladder. The patient underwent diagnostic hysteroscopy, cystoscopy, and full resection of the longitudinal vaginal septum as well as drainage of hematocolpos, which are the main treatment of the patient with OHVIRA.

PURPOSE: Ureteral duplication is a relatively common congenital urinary tract abnormality that can be associated with various clinical problems such as vesicoureteral reflux (VUR), hydronephrosis, and ectopic ureters. The purpose of this study was to analyze the clinical characteristics of pediatric patients with recently diagnosed ureteral duplication and to identify any differences from those described in previous reports.METHODS: We retrospectively reviewed the clinical characteristics and course of pediatric patients who were diagnosed with ureteral duplication between January 2008 and June 2017.RESULTS: A total of 32 pediatric patients were diagnosed with ureteral duplication during the study period. The male to female ratio was 1:2.2. Twenty-seven patients (84.4%) were first diagnosed with ureteral duplication at less than 3 months of age, and 26 (81.3%) were first diagnosed by prenatal ultrasonography. Four of the 32 patients were diagnosed with bilateral ureteral duplication, for a total of 36 occurrences of ureteral duplication. In 17 occurrences of complete ureteral duplication (47.2%), other urinary tract anomalies were also found; namely, ureterocele (7), VUR (11), and ectopic ureter (5). However, none of the patients with incomplete ureteral duplication had ureterocele or VUR.CONCLUSION: With the advent of routine prenatal ultrasound, ureteral duplication is being diagnosed earlier than was previously possible, enabling timely treatment of the various accompanying urinary tract anomalies. Multicenter studies are needed to establish guidelines for standardized evaluation and treatment of ureteral duplication.

Hydronephrosis is the most common urogenital anomaly with the potential for obstructive process. And ultrasonography, as a first-line imaging modality, is a useful tool for evaluation of prenatal and postnatal hydronephrosis, even though evaluation of renal function is still needed. In this article, we review the common causes of congenital hydronephrosis and the sonographic findings of those diseases.

PURPOSE: This study assessed the incidence and outcome of congenital anomalies of the kidney and urinary tract (CAKUT) detected by prenatal ultrasonography METHODS: There were 906 cases of CAKUT detected by prenatal ultrasonography and postnatally confirmed at the Asan Medical Center from October 1989 to October 2007. We investigated the incidence and outcome of these cases by reviewing medical records retrospectively. RESULTS: The order of incidence was hydronephrosis, multicystic dysplastic kidney (MCDK), duplex kidney, vesico-ureteral reflux (VUR), single kidney, hydroureteronephrosis, ectopic kidney, polycystic kidney, ureterocele, and posterior urethral valve (PUV). There were 520 cases (57.4%) of hydronephrosis, and 20% of these needed an operation due to significant obstruction. MCDK was associated with other CAKUT in 25.4% of all cases. Approximately 57.9% of duplex kidney cases needed surgical treatment due to ureterocele and VUR. VUR had a male: female ratio of 10:1. Two out of seven cases of autosomal recessive polycystic kidney had progressed to chronic renal failure. Patients with PUV were relatively uncommon, and one out of nine cases progressed to end-stage renal disease. CONCLUSION: CAKUTs detected by prenatal ultrasonography were composed of various anomalies, and almost all of them had a good outcome without any intervention. However, in some cases, recurrent urinary tract infection or renal failure occurred, especially in bilateral cases. For further management, a long-term multicenter study is needed to investigate the precise incidence and outcome of each anomaly in the general population.

A paraurethral cyst is a rare congenital or acquired abnormality in females that is characterized by a round, yellow or orange-colored cystic mass on either side of the urethral meatus. We report a patient who presented with frequent, postvoiding dribbling. The important differential diagnostic considerations in infants and adults are an ectopic ureterocele, urethral diverticulum, cystocele and paraurethral tumors. Intravenous pyelography, voiding cystourethrogram, cystourethroscopy are essential for differentiating these lesions. This case of a paraurethral cyst was treated with complete excision.

PURPOSE: Non conservative treatment such as heminephrectomy is considered the treatment of choice when the upper pole kidney in children with a complete ureteral duplication complicated with ureterocele or ectopic ureter is nonfunctional. The postoperative outcome of the upper pole kidney with a complete ureteral duplication after pyeloureterostomy was evaluated, and we focused on those children with undetected functions on the upper pole kidney before surgery. MATERIALS AND METHODS: Between May 2002 and March 2006, we evaluated 28 children, 10 boys and 18 girls, who had undergone pyeloureterostomy for a complete ureteral duplication that was complicated with ureterocele or ectoplic ureter. Their mean age was 12.3 months. Ultrasound, 99mTc-dimercaptosuccinic acid(DMSA) scanning and voiding cystourethrography(VCUG) were performed preoperatively. The clinical courses were followed up with ultrasound at 1, 3, 6 and 12 months, and DMSA scanning was done between 6 and 12 months after surgery. The median follow-up period was 21.5 months. RESULTS: Among the 12 children with cortical thinning seen on ultrasound, 10 showed thickening of the renal cortex within 12 months. All 16 children with Grade III or less hydronephrosis on the upper pole kidney were downgraded, and 10 out of them showed complete resolution or Grade I hydronephrosis within 6 months. 4 cases with no visible photon uptake at the upper pole kidney preoperatively showed hot uptakes at the defective spot between 6 to 12 months after pyeloureterostomy. 5 out of 28 children had urinary tract infection(UTI) within 3 months after surgery; however, this was easily controlled with oral antibiotics. CONCLUSIONS: The function of the upper pole kidney is recovered within 1 year after pyeloureterostomy in most of the cases with a complete ureteral duplication, regardless of the severity of hydronephrosis at the upper pole kidney. Pyeloureterostomy can be an alternative treatment modality for treating a complete ureteral duplication that's complicated with ureterocele or ectopic ureter due to pyeloureterostomy's lower morbidity compared to non-conservative surgery such as heminephrecotmy.

PURPOSE: To review the clinical manifestations, indications and the management outcomes of adult patients with ureteroceles. MATERIALS AND METHODS: Between 1995 and 2006, 20 adult patients (9 females, 3 males) with ureteroceles were investigated for their clinical symptoms, type of ureterocele and renal function. The outcomes of surgical or conservative management, according to the patients' symptoms were also individually analyzed. The median follow-up was 38 months (12-50 months). RESULTS: The ages at diagnosis of the ureteroceles ranged from 19 to 70 years (mean 37.9 years). The ureterocele-related symptoms were flank pain (3), hematuria (1) and lower urinary tract symptoms (4). Two cases were incidentally detected with ultrasound (1) or computed tomography (1), and another 2 patients presented with non-specific flank pain or a hematuria. Eight patients exhibited an intravesical single system and 4 were associated with upper pole of a duplex system. Only one patient had an ectopic ureterocele, in which the orifice was located in the mid-urethra. The ureterocele-related symptoms were managed using a transurethral incision (5) or resection (1) of the ureterocele, with ureteroscopic stone retrieval (2). The symptoms were resolved after surgery, and there were no recurrence of symptoms or any deterioration of the renal function during follow-up. CONCLUSIONS: To diagnose an ureterocele in adult patients requires a high index of suspicion, as not all patients present with the typical clinical manifestations associated in children. Our results suggested that ureterocele-related symptoms are the main indication for surgery in adult patients. While methods with lower morbidity may be a useful, expectant treatment, they may also be an appropriate option for the management of incidentally detected ureteroceles.

BACKGROUND: As health screening examinations are becoming more popular, increasing number of patients are found to have hematuria. In case of isolated microscopic hematuria, when to refer these patients to urologists for cystoscopy to find bladder cancer has been a matter of debate. METHODS: From January 1998 to May 2004, 287 patients older than 50 years of age visited our clinic for the evaluation of hematuria. Of these patients, 50 isolated asymptomatic microscopic patients underwent cystoscopy for the evaluation of bladder cancer. Additionally, 275 patients were retrospectively analyzed who had been found to have urologic malignancy during the same period. RESULTS: There were 50 patients (9 men, 41 women) with asymptomatic isolated microscopic hematuria who agreed to undergo cystoscopy examinations. Cystoscopic findings included normal in 41 patients, benign prostatic hyperplasia in 2 patients, cystitis in 2 patients, ureterocele in 1 patient, bladder neck contracture in 1 patient, urethral stricture in 1 patient, bladder diverticulum in 1 patient and ureter stone in 1 patient, but no bladder cancer was detected. In retrospective analysis, among 22 patients with bladder cancer and initial asymptomatic microscopic hematuria, one patient was found to have bladder cancer by cystoscopy after negative findings on radiologic examinations and urine cytology. CONCLUSION: Cystoscopy in patients with asymptomatic isolated microscopic hematuria to diagnose bladder cancer seems to be limited in the cost and efficacy aspect in the current study. A prospective multicenter study is needed establish the criteria for cystoscopy in these patients.

OBJECTIVE: Routine maternal ultrasonography has revealed a very high incidence of fetal hydronephrosis. However, there is little data available, in Korea, on the natural progress of prenatal hydronephrosis. Therefore, to help in the management of patients, the antenatal course and neonatal follow-up data of isolated fetal hydronephrosis were analyzed. METHODS: Prenatal diagnosis, etiologies, clinical characteristics, and outcome were studied retrospectively in 77 cases of unilateral and bilateral prenatal hydronephrosis from January 2000 to March 2004. Cases were classified as mild (7 mm > or =, < or = 10 mm), moderate (10 mm >, < or = 15 mm), and, severe (15 mm >) prenatal hydronephrosis as depending on the renal pelvis anteroposterior diameter. Fisher's exact test and Chi-square test were used for statistical analysis. RESULTS: The etiologies of prenatal hydronephrosis were ureteropelvic junction obstruction 45 (58.4%), vesicoureteral reflux 2 (2.6%), ureterocele 1 (1.3%), and urethra obstruction 1 (1.3%). At delivery, 18 cases were normal kidneys, and during the follow-up periods, 10 cases resolved spontaneously. Mild, moderate, and severe hydronephrosis were present in 30 (38.9%), 38 (49.4%), and 9 (11.7%) respectively. Operations were performed in 2/38 (5.3%) of moderate cases, and 7/9 (77.8%) of severe cases. CONCLUSION: Most of prenatal hydronephrosis diagnosed by ultrasonography disappeared postnatally and the needs for postnatal operations were rare. It is suggested that hydronephrosis in the fetus or neonate dose not necessarily imply the presence of an obstructive uropathy or a significant functional abnormality and the reassurance of parents and follow up evaluation of the neonate during perinatal period may be needed.

PURPOSE: Our experience of upper moiety in the complete duplex system was retrospectively analyzed to determine its optimum management. MATERIALS AND METHODS: Between 1988 and 2003, 27 patients were treated with the complete duplex system. Fifteen patients had ureterocele (9 intravesical, 6 ectopic) and the other 12 had an ectopic ureter. In all cases, excretory urography, ultrasonography, voiding cysto-urethrogram (VCUG) and dimercaptosuccinic acid (DMSA) renal scan were performed. The initial treatment was performed using salvage (transurethral incision or ureteropyelostomy) or non-salvage procedures (upper pole nephrectomy or nephrectomy). The median follow-up was 30 (13-48) months. RESULTS: The 27 patients were divided into three groups based on the function of the upper moiety from the DMSA renal scan - <10%; 13 patients (group A), 10-15%; 3 patients (group B), > or=15%; 11 patients (group C). In group A, upper pole nephrectomy was performed in 9 patients, a total reconstruction in 3 and a nephrectomy in 1. In group B, an upper pole nephrectomy was initially performed, with an ureteropyelostomy and transurethral incision (TUI). In group C, all patients received a transurethral incision as the initial treatment. The ipsilateral renal function was well conserved in the cases of upper pole nephrectomy, with no complications. Patients initially receiving salvage procedures showed a significant improvement and conservation of the ipsilateral renal function, but 4 patients required additional operative management due to moderate to severe vesicoureteral reflux (VUR), recurrent urinary tract infection and decreased renal function of the upper moiety. CONCLUSIONS: Salvage procedures are a preferable adequate therapeutic modality for the complete duplex system with a well conserved renal function.
