Diagnostic clues, pitfalls, and imaging characteristics of '-celes' that arise in abdominal and pelvic structures.

Abdom Radiol (NY) 2020 Apr 30. Epub 2020 Apr 30.

Department of Internal Medicine, Pratumthani Hospital, 7 Ladlumkaew Muang District, Pratumtani, 12000, Thailand.

'-Celes' is an ancient Greek language suffix that means 'tumor,' 'hernia,' 'swelling,' or 'cavity.' There are many '-celes' in the abdomen and pelvis that may be encountered during routine imaging interpretation, including santorinicele, choledochocele, ureterocele, lymphocele, mucocele, rectocele, cystocele, peritoneocele, varicocele, spermatocele, hydrocele, hematocele, pyocele and syringocele. Most '-celes' are detected incidentally at imaging for other clinical indications, but some deserve more attention due to a range of clinical symptoms or functional disorder that can adversely affect patient quality of life.

Ipsilateral ureteroureterostomy: does function of the obstructed moiety matter?

J Pediatr Urol 2019 Feb 20;15(1):50.e1-50.e6. 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.

Introduction: Symptomatic pediatric ureterocele has diverse manifestations, making evidence-based management impractical. Thus, detailed visualization of ureterocele anatomy prior to first surgical incision is invaluable. Retrograde ureterocelogram (RUC) is a simple, underutilized radiologic technique that can be performed during cystoscopy. Read More

Unusual variant of inverted Y ureteral duplication with an ipsilateral seminal vesicle cyst and renal dysgenesis.

Ann R Coll Surg Engl 2017 Jan 23;99(1):e19-e21. Epub 2016 Sep 23.

Mohammed V Military Hospital , Rabat , Morocco.

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. Read More

New minimally invasive technique for cystoscopic laser treatment of fetal ureterocele.

Ultrasound Obstet Gynecol 2017 Jul 30;50(1):124-127. Epub 2017 May 30.

Department of Pediatric Urology, Fondazione IRCCS Ca' Granda, Ospedale Maggiore Policlinico, Milan, Italy.

Prenatal ultrasound detection of fetal ureterocele with bilateral hydroureteronephrosis, obstruction of the bladder outlet and progressive amniotic fluid reduction have been associated with a significant risk of end-stage chronic renal disease after birth. Fetal cystoscopic laser incision of the ureterocele, using standard 3.5-mm fetoscopic access to the amniotic cavity and the fetal bladder with the aim of relieving the bladder outflow obstruction to preserve renal function, has been reported previously in a case with a favorable outcome.
