Inverted-Y ureteral duplication is one of the rarest anomalies of ureteral branching. We encountered a 20-year-old female patient with persistent incontinence even after nephrectomy for ectopic ureteral insertion into the vagina. She had inverted-Y ureteral duplication between the bladder and vagina, and urine was being transported from the bladder to the vagina. To the best of our knowledge, this is a rare case of inverted-Y ureteral duplication with ectopic ureteral insertion into the vagina as well as the ureter into the bladder, which became apparent due to persistent urinary incontinence even after nephrectomy...

Inverted Y malformation is a rare variant of ureteral duplication with a marked female predominance. We describe a case of inverted Y ureteral duplication with concurrent ectopic ureteral insertion into a seminal vesicle cyst, a ureterocoele and renal dysgenesis, which occurred in a 29-year-old man with lower urinary tract symptoms, haematospermia and postcoital discomfort. To our knowledge, this is the first reported case with this constellation of urogenital abnormalities.

Ectopic insertion of the ureter in the genitourinary tract is a rare congenital disorder, usually associated with ureteral duplication. Identification of the insertion open is critical for ureteric re-implantation. However, the challenge in the diagnosis of ectopic insertion of the ureter usually is to identify its insertion, particularly when the affected ureter is not dilated. Multi-detector computed tomography (MDCT) urography with nonionic iodinated contrast media delineates the ureteric course in the normal functioning kidney in the excretory phase [1]...

INTRODUCTION: Robotic technology has been increasingly utilized for complicated reconstructive surgeries in pediatric urology, such as ureteroureterostomy (UU). The literature is limited regarding the performance of minimally invasive UU in children, and the existing published series utilize indwelling ureteral stents. We sought to report on our pediatric experience with robot-assisted laparoscopic (RAL)-UU using a temporary ureteral catheter in duplex systems with ureteral ectopia. METHODS: A retrospective chart review was performed of all pediatric patients who underwent RAL-UU at a single institution over a 2-year period...

A blind-ending bifid ureter is an anatomic variant of ureteral duplications. There are three forms of blind-ending bifid ureter, classified depending on their location. A proximal blind-ending bifid ureter is the most common subtype of this congenital anomaly. Most patients are asymptomatic and only show symptoms after the complication has occurred. These complications include stone formation, vesicoureteric reflux, and ureteral tumor. Intravenous urography is usually used to diagnose bifid ureter; voiding cystourethrography, photofluoroscopy, cineroentgenography, cystoscopy with retrograde pyelography, computed tomography (CT), multidetector CT, and magnetic resonance urographies are other imaging methods used...

Bilateral complete duplication of the ureters is a rare condition. We report a case of an adult male patient with bilateral complete duplication of the ureters, with a single stone simultaneously obstructing each of the four ureteral limbs. Multiple bilateral renal stones were awlso demonstrated in the imaging studies. The ureteral stones ranged from 7 to 23 mm in length and 5-11 mm in width. Ureteroscopy and holmium laser lithotripsy for the ureteral stones were done sequentially in the four ureteral limbs, in a single session...

Duplication of inferior vena cava is an uncommon abnormality and is important in daily today practice for vascular surgeons, radiologist and urologist especially during retroperitoneal surgeries and treatment of thromboembolic disease. Radiologically, Duplicated IVC can be mistaken for lymphadenopathy or left pyeloureteric dilatation. Crossed fused kidney with a single ureter defy the embryological theory of ureteric bud crossing the opposite side and induce nephron formation associated anomaly of Duplication of inferior vena cava and malrotation of gut are not reported in a same patient...

A 60-year-old woman with a history of breast cancer presented with bilateral obstruction of bilaterally duplicated renal collecting systems secondary to extrinsic compression from metastatic pelvic lymphadenopathy. Bilateral JJ ureteric stents were inserted, resulting in some improvement of renal function but a failure to normalise completely. Repeat computed tomography demonstrated bilateral duplex collecting systems with persisting obstruction of the undrained moieties. Selective puncture was performed to decompress the obstructed renal moieties for bilateral nephrostomy catheter insertion...

Duplex collecting systems are the most commonly encountered anomaly of the urinary system. Complete duplex system with an H shaped ureter is a very rare situation. There are only two reported H ureter cases in the literature. Herein, we aimed to present an H shaped ureter case, which was identified while performing ureterorenoscopy to a 48-year-old female patient due to a right distal ureteral stone.

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...

INTRODUCTION AND OBJECTIVE: While open ureteral reimplantation remains the gold standard for surgical treatment of vesicoureteral reflux (VUR), minimally invasive approaches offer potential benefits. This study evaluated the outcomes of children undergoing complex robot-assisted laparoscopic ureteral reimplantation (RALUR) for failed previous anti-reflux surgery, complex anatomy, or ureterovesical junction obstruction (UVJO), and compared them with patients undergoing open extravesical repair...

BACKGROUND: Minimally invasive surgery is the current approach to perform heminephroureterectomy (HN) in children. This can be obtained through a transperitoneal (TP) or a retroperitoneal approach. Here, we report our experience using a TP approach. MATERIALS AND METHODS: From 2005 to 2014, 22 TP laparoscopic upper poles HN were performed at our institution. There were nine girls and 13 boys aged between 20 months and 6 years (mean age 3.9). Eight patients were diagnosed prenatally, 17 patients presented with urinary tract infection (UTI) and three with vomiting and failure to thrive...

Renal duplication accompanied by ureteral ectopia is an uncommon urinary congenital abnormality. We report the case of a 21-year-old girl who suffered from lifelong continuous urinary leakage. She was finally diagnosed with bilateral duplicated collecting systems complicated with right ectopic ureteral orifice - an extremely rare case. The patient underwent ureteric re-implantation for the ectopic side, and her urinary incontinence ceased soon thereafter. In this case, traditional imaging failed to show the exact insertion of an ectopic ureter...

Retrocaval ureter (pre-ureteral vena cava) is an uncommon congenital anomaly that causes ureteral obstruction by external compression. Although right retrocaval ureter is a common entity, left retrocaval ureter is extremely rare. A left retrocaval ureter is usually associated with situs inversus or duplicated inferior venacava (IVC). An isolated left retrocaval ureter with single left-sided IVC is even rarer and only four cases have been reported in the literature. We present images of a case with isolated left retrocaval ureter with a single left-sided IVC without situs inversus...

Pallister-Hall syndrome (PHS) is a rare disorder caused by mutations in GLI3 that produce a transcriptional repressor (GLI3R). Individuals with PHS present with a variably penetrant variety of urogenital system malformations, including renal aplasia or hypoplasia, hydroureter, hydronephrosis or a common urogenital sinus. The embryologic mechanisms controlled by GLI3R that result in these pathologic phenotypes are undefined. We demonstrate that germline expression of GLI3R causes renal hypoplasia, associated with decreased nephron number, and hydroureter and hydronephrosis, caused by blind-ending ureters...

Urine leak after nephron-sparing surgery is a difficult and morbid situation that may delay recovery and necessitate additional hospitalization and intervention. The use of cryoablation to treat a 34-year-old woman with persistent urine leak after robotic-assisted partial nephrectomy is described. Surgery was performed to treat ureteral duplication that resulted in recurrent urinary tract infections and back pain. Cryoablation was performed with computed tomography guidance, targeting urine extravasation observed after the administration of intravenous contrast medium...
