Orthotopic ureteroceles may present with various symptoms, such as bladder irritability, flank pain, stone formation or recurrent urinary infections. When symptomatic, excretory urography often demonstrates varying degrees of hydronephrosis. We herein review a series of 12 patients in whom endoscopic ureteroneocystostomy (distal incision of the ureterocele) was performed. The procedure, and its theoretical advantages and indications are discussed. The results indicate excellent therapeutic benefit from this minimally invasive technique.

A case of ectopic ureterocele in a 21-year-old male is reported. His chief complaint was right flank pain. We diagnosed ectopic ureterocele in right complete ureteric duplication with upper pole and right heminephrectomy was performed. Postoperative course was uneventful and ureterocele was markedly collapsed. The 10 reported cases with adult male ectopic ureteroceles including our case in Japan are reviewed and some characteristics of this entity are discussed.

25-year-old previously healthy male presented with dysuria and bilateral flank pain. Abdominal radiography and computed tomography revealed bilateral orthotopic ureteroceles with significant calculi. Bilateral endoscopic ureterocele incision and ureteroscopy were used for complete stone clearance. Symptoms resolved after treatment, and follow-up voiding cystourethrogram performed at 3 months revealed no evidence of vesicoureteral reflux. Adult orthotopic bilateral ureteroceles with calculi is a rare clinical entity amenable to endoscopic management.

A 36-year-old man with right flank pain presented to our institution. Intravenous urography showed mild dilatation of the right pyelocaliceal system and large filling defect in the vesical lumen. Computed tomography revealed the right kidney to be smaller than the left, and with chronic pyelonephritis. The right ureter passed behind the inferior vena cava at the level of the pelvic-ureteral junction. The middle and lower ureter was dilated above a large ureterocele. Cystourethrography showed right vesicoureteral reflux. The patient underwent a resection of the ureterocele with reimplantation of the ureter. Follow-up at 3 months demonstrated resolution of the dilatation of the right ureter.

We report a case of a 7-year-old boy with a voluminous 8.5-cm "cobra-head" calculus in a duplex system ureterocele causing flank pain, hematuria, and infection. Combined cysto-ureteroscopy and percutaneous cystolithotomy enables dependent ureterocele incision along its inferolateral border and efficient stone clearance in a single minimally invasive procedure. Protracted and repeated urethral instrumentation is avoided.

Transurethral endoscopic incision is an established treatment option for management of obstructing ureterocele. It can be performed using monopolar electrocautery or holmium laser as an energy source. The present study was carried out to evaluate outcomes of transurethral ureterocele incision (TUI) by two different energy sources, i.e., monopolar electrocautery versus holmium laser. A retrospective review of the data of all patients who underwent endoscopic TUI from 2007-2017 was performed. Preoperative clinical, biochemical, and radiological characteristics and operative parameters were reviewed and compared between the two groups. Associated stone in the ureterocele was fragmented using pneumatic lithotripter or Mauermeyer stone punch forceps in the electrocautery group and holmium laser in the laser group. Statistical analysis was performed using IBM SPSS version 21.0. Chi-squared test was used for categorical/dichotomous variables. Unpaired t test was used for continuous variables. Out of total 44 patients, 28 patients had duplex system ureterocele and 16 patients had single system ureterocele. Mean age was 18.5 + 7.4 years (range 14-26 years). Six patients had associated stones in the ureterocele. Most common presentation was flank pain followed by urinary infections and bladder outlet obstruction. Preoperative vesico-ureteric reflux was seen in 18% patients. Monopolar TUI was performed in 20 patients and laser-TUI in 24 patients. Three patients had associated stone in ureterocele in each group. Fragmentation of stone was successfully done with holmium laser without changing the instrument and with less associated surgical morbidity in the laser group. Postoperative successful decompression was evident in 38 (90%) patients. Renal parenchyma thickness was improved on ultrasound scan and renal scan showed non-obstructed system in all patients at follow-up. Both laser and monopolar incision have similar efficacy in decompressing the ureterocele in long-term follow-up. However, laser has added advantage of stone lithotripsy with the same instruments with lesser morbidity and lower incidence of persistent reflux.
