Ipsilateral ureteroureterostomy: does function of the obstructed moiety matter?

J Pediatr Urol 2018 Aug 20. Epub 2018 Aug 20.

Pediatric Urology, Children's Hospital of Philadelphia, PA, USA. Electronic address:

Purpose: Upper pole nephrectomy has been the traditional surgical management of children with poorly functioning upper pole moieties in duplex renal collecting systems having ureteral ectopia and ureterocele. However, ablative surgery confers a risk of functional loss to the remnant moiety due to vasospasm or vascular injury. It was hypothesized that ipsilateral ureteroureterostomy (IUU) is a safe and feasible approach for the management of these patients and that residual function in the obstructed upper pole does not affect surgical outcomes.

Ureterocele is a congenital anomaly, in which there is mal-development of the caudal segments of the ureter. There is a female preponderance with most cases seen in Caucasians. Among the reported complications of this condition, chronic renal failure occurring in the setting of ureterocele has not been well documented. Read More

Fetoscopic laser surgery to decompress distal urethral obstruction caused by prolapsed ureterocele.

Ultrasound Obstet Gynecol 2015 Nov 12;46(5):623-6. Epub 2015 Oct 12.

BCNatal, Barcelona Center for Maternal-Fetal Medicine and Neonatology, Hospital Clínic and Hospital Sant Joan de Déu, IDIBAPS, University of Barcelona, and Centro de Investigación Biomédica en Red de Enfermedades Raras (CIBERER) - Maternal-Fetal Medicine and Neonatology, Barcelona, Spain.

We report on the successful use of fetoscopic surgery to treat a case of prolapsed ureterocele in a female fetus. At 21 weeks' gestation, a double renal system with an intravesical ureterocele obstructing the bladder outlet was diagnosed, causing severe megacystis, bilateral hydronephrosis and progressive oligohydramnios. Ultrasound evaluation following referral to our center confirmed severe bilateral hydronephrosis with pelvic and calyceal dilatation, but amniotic fluid volume was normal and the ureterocele was not visualized in the bladder.

Diagnosis and Management of a Prolapsing Intravesical Ureterocele in a Man.

J Endourol Case Rep 2015 1;1(1):9-10. Epub 2015 Oct 1.

The Smith Institute for Urology, North Shore-Long Island Jewish Health System, New Hyde Park, New York.

Given the low incidence and delayed diagnosis, ureterocele management in the adult population is poorly described in the literature. Moreover, there is only one case report characterizing the condition with prolapse in an adult male. Approaches to therapy include transurethral incision or puncture with or without a combined percutaneous approach, and excision with or without partial nephrectomy for a duplicated system with a nonfunctioning upper pole moiety.

IMAGING DIAGNOSIS--URINARY BLADDER DUPLICATION IN A CAT.

Vet Radiol Ultrasound 2015 Jul-Aug;56(4):E48-53. Epub 2014 Aug 19.

Department of Pathology, The Animal Medical Center, New York, NY, 10065.

A female kitten presented for chronic, intermittent, antibiotic-responsive urinary incontinence and chronic kidney disease. Abdominal ultrasound identified bilateral pelvic/ureteral dilation and three closely apposed thin-walled fluid-filled structures in the caudal abdomen, extending toward the pelvic inlet. Excretory urography and negative contrast cystography identified contrast medium accumulation from the dilated ureters into two tubular soft tissue masses of the caudal abdomen, with subsequent gradual filling of a more cranially located urinary bladder.

Laser ablation in the management of obstructive uropathy in neonates.

J Endourol 2015 May 5;29(5):611-4. Epub 2014 Sep 5.

1 Department of Urology, Columbia University Medical Center , New York, New York.

Introduction: Endoscopic management of posterior urethral valves and congenital ureteroceles is the current standard to relieve the obstruction. While the most commonly used techniques involve cystoscopic incision with cold knife or electrosurgery, an alternative is to ablate the obstructive tissue with laser energy. With increasing prenatal diagnoses, there has been an increasing shift in the timing of intervention toward earlier periods. Read More

Ureteroureterostomy irrespective of ureteral size or upper pole function: a single center experience.

J Pediatr Urol 2014 Aug 2;10(4):616-9. Epub 2014 Jun 2.

Nationwide Children's Hospital, Division of Pediatric Urology and The Ohio State University Medical Center, Timken Hall, G280, 700 Children's Drive, Columbus, OH 43205, USA. Electronic address:

Objective: Although ureteroureterostomy (UU) is an established procedure for the treatment of duplex anomalies, there may be a reluctance to apply this approach to patients with poor upper pole function and/or marked degrees of ureteral dilation.

Methods: An institutional review board (IRB)-approved retrospective analysis of all patients undergoing UU between 2006 and present was performed. All patients underwent an end-to-side anastomosis with a double-J stent left in the lower pole ureter. Read More

One of the basic abdominal organs that is assessed during transabdominal ultrasound examination for urological reasons is the urinary bladder. The bladder must be filled with urine. This is a prerequisite for a reliable assessment and, at the same time, an acoustic window in examining adjacent structures and organs, for instance the prostate gland. Read More
