prenatal incision of Ureterocele causing bladder outlet obstruction a multicenter case series
Prenatal Diagnosis, 2017Co-Authors: G E Chalouhi, Anne Maude Morency, Roland De Vlieger, J M Martinez, Thomas Blanc, Ryan Hodges, A Gueneuc, Greg Ryan, Jan DeprestAbstract:We reviewed data from a cohort of fetuses with Ureterocele diagnosed and operated prenatally in four fetal therapy centers. Inclusion criteria were: (1)Ureterocele confirmed on detailed fetal ultrasound examination, (2)absence of additional fetal malformations (3)fetal intervention to decompress the Ureterocele with local institutional review boards’ approval. Data on sonographic follow-up, obstetrical, neonatal outcome and postnatal evaluation were collected. Ten cases of prenatally treated Ureterocele are described. Six cases benefited from a fetoscopy for laser incision and decompression, two cases had an ultrasound guided puncture before resorting to a fetoscopy with laser incision, one case had a balloon catheterization under ultrasound guidance and one case had an ultrasound-guided opening of the Ureterocele with a laser fiber passed through a 20G needle. Mean GA at diagnosis was 21.6GW. Two cases underwent TOP. The remaining eight cases recovered normal amniotic fluid volume, and delivered a live-born child at a mean GA of 38.6GW with normal creatinine levels during the first week of life. Prenatal incision provided complete treatment of severely obstructive Ureteroceles in 80% of the cases and allowed improvement of urinary electrolytes, renal size and echogenicity, bladder filling in all survivors and recollection of normal amniotic fluid volume, in case of oligoanhydramnios.

impact of prenatal diagnosis on the morbidity associated with Ureterocele management
The Journal of Urology, 2002Co-Authors: Jyoti Upadhyay, Stephane Bolduc, Luis H Braga, W Farhat, Darius J Bagli, Gordon A Mclorie, Antoine E Khoury, Alaa ElghoneimiAbstract:Purpose: We postulated that prenatal detection of Ureteroceles has a positive impact on the natural history and clinical outcome of Ureteroceles in duplex system.Materials and Methods: Between 1992 and 2000, 95 children underwent surgery for a Ureterocele in a duplex system. We evaluated the impact of prenatal diagnosis in 40 cases versus postnatal diagnosis in 55 on morbidity, as measured by postoperative urinary tract infection and secondary procedures, while controlling for Ureterocele type and the initial surgical approach.Results: Mean followup in the 2 groups was 3.9 years. Preoperatively the reflux rate was 51% in the prenatal and 66% in the postnatal groups. Preoperatively urinary tract infections were less common in the prenatal group (12% versus 84%). Mean age at initial intervention in prenatally and postnatally diagnosed patients was 6 and 31 months, respectively. Postoperatively the urinary tract infection rate was double in postnatally diagnosed patients. Overall postoperatively reflux was s...

outcomes of endoscopic incision for the treatment of Ureterocele in children at a single institution
The Journal of Urology, 2015Co-Authors: James C Sander, D R Roth, E T Gonzales, Aylin N Bilgutay, Irina Stanasel, Chester J Koh, Nicolette Janzen, Abhishek SethAbstract:Purpose: We assessed outcomes in children with Ureterocele after transurethral incision at our institution between 2001 and 2014, focusing on end points of vesicoureteral reflux, improvement of hydronephrosis and need for second surgery.Materials and Methods: We performed chart reviews of 83 patients, collecting information including age at transurethral incision, gender, renal anatomy, Ureterocele location, indication for transurethral incision, and preincision and postincision vesicoureteral reflux and hydronephrosis status. Patients were divided into those with single system and duplex system Ureteroceles, and intravesical and extravesical location for analysis. Statistical evaluations were performed with the Wilcoxon rank test and Fisher exact test.Results: Transurethral incision was performed at a mean age of 34.2 months in patients with single system Ureterocele and 8.9 months in those with duplex system Ureterocele (p <0.0001). Cure rates (improvement of hydronephrosis and absence of vesicoureteral...

prenatal diagnosis of a prolapsed Ureterocele with magnetic resonance imaging
Urology, 2003Co-Authors: Selami Sozubir, Linda A. Baker, Armando J Lorenzo, Diane M Twickler, David H EwaltAbstract:Ectopic Ureterocele with ureteral duplication is the most common type of Ureterocele found in children. Early accurate diagnosis is desirable to decrease the risk of urosepsis and renal damage. Prenatal imaging with ultrasonography detects the vast majority of Ureteroceles; however, in some cases, the diagnosis may remain in doubt. We report on the use of magnetic resonance imaging to clarify the prenatal diagnosis of a prolapsed Ureterocele.
