Prenatal intervention for a large ureterocele in a male fetus causing lower urinary tract obstruction "Society of Fetal Urology Case Reports, Fall 2024". A male fetus at 20 weeks of gestation presented with severe bilateral hydroureteronephrosis and distended bladder due to a large ureterocele. A percutaneous ureterocele puncture at 21+3 weeks aimed to decompress the ureterocele, unclog the lower urinary tract, and prevent renal damage. Post-puncture, the ureterocele decompressed, with improved left hydronephrosis and a normal right kidney. Postnatal follow-up showed bilateral HUN improvement. At term, the baby was delivered without complications, but the ureterocele refilled, necessitating a postnatal transurethral incision. This case highlights the feasibility and benefits of prenatal
Pop-off mechanisms in fetal megacystis: extravasation, umbilical cord cyst, ureterocele and megaureter. To analyze comprehensively the incidence, antenatal ultrasound characteristics and prognostic implications of antenatal pop-off mechanisms of the fetal urinary system in pregnancies with suspected fetal megacystis. This was a retrospective multicenter study of pregnancies with suspected fetal megacystis conducted across all academic hospitals in The Netherlands. Three antenatal pop-off mechanisms were identified: presence of an umbilical cord cyst (UCC), extravasation of urine into the intraperitoneal space (ascites) or perirenal subcapsular (urinoma), and megaureter/ureterocele. Cases that exhibited two different pop-off mechanisms, underwent vesicoamniotic shunt placement or had unclear
Lower urinary tract reconstruction for ectopic ureterocele: What happens in the long-term follow-up? We aimed to analyze the long-term clinical and lower urinary tract function outcomes in children with duplex system ectopic ureterocele who underwent ureteroneocystostomy and ureterocelectomy. Fifty-one patients (28 females, 23 males) who underwent a series of surgical interventions including lower urinary tract reconstruction in childhood for duplex system ectopic ureterocele in our center between 1998 and 2019, were retrospectively reviewed. The demographic and clinical data, surgical history, and the indication for ureterocelectomy were noted. Lower urinary tract dysfunction (LUTD) status was assessed through dysfunctional voiding symptom scores (DVSS) and uroflowmetry in all patients
Concurrent Multicystic Dysplastic Kidney, Posterior Urethral Valves, and Obstructive Ureterocele in a Male Pediatric Patient: A Case Report. Congenital anomalies of the kidney and urinary tract (CAKUT) are diagnosed in approximately 3-6 per 1000 live births and represent a spectrum of urologic conditions impacting the kidneys, ureter, bladder, and urethra. Although both are considered under the classification of CAKUT, there is no known unifying pathophysiologic mechanism for ureteroceles and posterior urethral valves with only 1 case report noted in the literature. Herein we report the only documented case of a patient with CAKUT related to posterior urethral valves, ureterocele, and multicystic dysplastic kidney.
The left ureterocele and stone of calyceal diverticulum in the patient with bilateral incomplete duplex kidneys managed by flexible ureteroscopy: a case report and literature review. Duplex kidneys are one of the most common renal congenital abnormalities, mostly asymptomatic and of no clinical significance. There are little reports about the left ureterocele and stone of calyceal diverticulum in patients with bilateral incomplete duplex kidneys managed by flexible ureteroscopy. A 69-year-old Chinese woman was presented with left waist pain for 1 month. A preoperative computed tomography (CT) scan and intravenous pyelogram revealed the left ureterocele which located in the left ureterovesical junction, and stone of calyceal diverticulum which located in the upper kidney of left incomplete duplex
Kidney triplication with ectopic ureterocele: a case report. Kidney triplication is a rare urological abnormality. Association of triplex kidney and ureterocele is out of ordinary. Treatment of such patients usually implies heminephrureterectomy of the upper moiety. We report a case of a saved function of the upper moiety after minimal invasive surgical procedure. 5-year old girl complained for continuous wetting. Examination revealed 3 - segmented left kidney with pelvi-ureteric dilation of the upper moiety, IV grade vesicoureteral reflux in the upper moiety, cervical ectopic ureteral orifice of the upper moiety and a commune ureteral orifice of the lower segments. An endoscopic laser dissection of ureterocele was performed. Drainage of the upper moiety of triplex kidney was restored
A Rare Case of Prolapsed Ureterocele with Large Redundant Flap After Unroofing in Adult Female. We present a case of 26-year female who presented with acute urinary retention and vulvar mass. She denies any urinary complaints in the past except for occasional straining for voiding. Imaging revealed a prolapsed ureterocele, it was successfully managed with incision and excising a flap of ureterocele due to the risk of postoperative protrusion of the redundant ureterocele. On follow-up at 6 months she was voiding well without any complaints.
Unconventional Use of the Lithoclast to Aid in the Treatment of Large Distal Ureteral Stone Burden in a Patient With a Ureterocele. Large ureteral stone burden can present significant challenges for the urologist to treat. Here we present the retrograde use of the Lithoclast Select, in a dilated distal ureter after incision of a ureterocele. The patient is a 64 year-old female with large distal orifice a very large ureterocele was noted. The lower pole system was scoped and stone free. The ureter to the upper pole moiety was scoped and a large stone burden within the distal ureter was visualized. The Plasmacise Gyrus was used to incise the anterior part of the ureter by inserting the Plasmacise into the ureteral orifice and tenting it anteriorly. The 24-French nephroscope was then inserted
Bladder Paraganglioma Mimicking a Tumor Contained in a Ureterocele. Extra-adrenal pheochromocytoma is called paraganglioma. Paraganglioma near the ureterovesical junction can be confused with urothelial carcinoma in a ureterocele. Urinary metanephrine can be an indicator for bladder paraganglioma. Metaiodobenzylguanidine scintigraphy is an excellent method not only for distinguishing bladder
Transurethral incision as initial option in treatment guidelines for ectopic ureteroceles associated with duplex systems. Treatment strategies for children with ectopic ureteroceles (EUs) and duplex collecting systems or vesicoureteral reflux are controversial. Transurethral incision (TUI) of EUs associated with duplex systems has been considered only as a temporizing technique. This study aimed to evaluate whether primary TUIs could be considered as an initial treatment option in EUs with duplex systems. Forty-seven children with EUs associated with duplex systems underwent primary TUIs at our institution between November 2007 and October 2017. We retrospectively analyzed patient characteristics such as age, sex, upper tract status, ureterocele location, differential renal function
A Large Stone Within a Ureteroceles: A Diagnostic Pitfall and the Utility of Holmium Laser Deroofing as a Viable Surgical Option We describe a case of a partial unilateral duplex system and ureterocele containing a 4 cm stone in a 66-year-old woman who presented with renal colic. Cystoscopic stone removal and deroofing of the ureterocele were performed and a ureteral stent was placed for a total of 6 weeks. Our case is unique as it highlighted the diagnostic pitfalls of ureteroceles, especially when obscured by a large calculus. We also described the use of a Holmium laser to simultaneously incise the ureterocele and fragment the calculus.
Adult Bilateral Ureteroceles Presenting with Lower Urinary Tract Symptoms and Acute Urinary Retention Ureterocele is a well-known pathologic entity in the pediatric urology population but remains a diagnostic and treatment challenge in the adult population. Adult ureteroceles remain a diagnostic challenge for the adult urologist. Its prevalence is estimated between 1/500 and 1/4000 patients with a wide variety of clinical presentations. We present the case of a 30-year-old female patient who presented with severe lower urinary tract symptoms (LUTS) and acute urinary retention secondary to prolapsing bilateral single-system orthotopic ureteroceles. She was successfully treated with transurethral unroofing of her bilateral ureteroceles and she is currently asymptomatic. This case represents
Laparoscopic Surgery for Seminal Vesicle Cysts and Ureterocele with Urination Disorder: A Case Report of Zinner Syndrome Zinner syndrome is defined as seminal vesicle cysts with ipsilateral renal agenesis and an ectopic ureter. Symptomatic cases are very rare. In this article, we present a laparoscopic approach for a case of Zinner syndrome. The patient was a 21-year-old male with difficult urination. A right seminal vesicle cyst and right kidney agenesis associated with ureterocele were found on examination and he was diagnosed with Zinner syndrome. First, we performed transperineal puncture of the ureterocele because it closed the bladder neck during voiding. Although voiding symptoms temporarily improved, the ureterocele recurred soon and the urination disorder was reexacerbated. Next, we
An adult ureterocele complicated by a large stone: A case report Ureterocele is a cystic dilatation of the lower part of the ureter. It is a congenital anomaly that is associated with other anomalies such as a duplicated system, and other diseases. It poses a great challenge owing to its numerous types and clinical presentations. Its incidence is 1 in every 4000 individuals. One of its presentations in the adult population is the presence of a stone, usually a solitary stone, inside the ureterocele. We are reporting a case of an adult ureterocele complicated by a large calculus; managed endoscopically with transurethral deroofing of the ureterocele followed by cystolitholapaxy. A literature review was also conducted. The pathogenesis of ureteroceles is not well understood, however many
Prevalence and risk factors of symptomatic urinary tract infection after endoscopic incision for the treatment of ureterocele in children. To clarify the impact of endoscopic incision (EI) for ureterocele as an initial procedure, by performing a retrospective chart review, focusing on the prevalence of and risk factors for symptomatic urinary tract infection (UTI) after EI. In the present study we included children with ureterocele, managed between September 1994 and April 2016, who were observed conservatively without additional surgical management after EI. Ureterocele was categorized as intravesical or ectopic. Symptomatic UTI was defined as either recurrent non-febrile or febrile UTI. The prevalence of and risk factors for symptomatic UTI were analysed using Cox proportional hazard
