Dorsal lumbotomy for pediatric upper pole hemi-nephrectomy: Back (door) to the future?

J Pediatr Urol 2020 May 7. Epub 2020 May 7.

Faculty of Medicine, University of British Columbia, Vancouver, BC, Canada; Department of Urologic Sciences, University of British Columbia, BC Children's Hospital, Vancouver, BC, Canada. Electronic address:

Introduction: Upper pole heminephrectomy (UHN) is performed for two main indications in children: ectopic ureterocele and duplication anomalies with upper pole ectopy, both in the context of a poorly functioning upper pole moiety. Current popular techniques for conducting UHN include laparoscopic (LPN) and robot-assisted laparoscopic (RAPN).

Objective: To evaluate outcomes following dorsal lumbotomy (DL), an open approach used historically for pyeloplasty and pyelolithotomy, and in which no clinical trials or exclusive case-series have been conducted for upper pole hemi-nephrectomy (UHN) in children. Read More

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.

Department of Paediatric Urology, Leeds General Infirmary, Leeds, LS1 3EX, UK. Electronic address:

Introduction: Duplex systems can be complicated by reflux, ureterocele, obstruction (most commonly PUJ in a lower moiety) and wetting secondary to an ectopic ureteric insertion in girls. The decision making algorithm for selection of surgical approach is complex and there is no consensus. The authors described the outcomes following an upper urinary tract approach in 2011(1) and now compare these results in a similar group of patients managed using a lower approach. Read More

Indian J Urol 2020 Jan-Mar;36(1):26-31

Department of Medicine and Aging Sciences, "G. d'Annunzio" University of Chieti-Pescara, Chieti, Italy.

Introduction: Few case series report the use of holmium: yttrium-aluminum-garnet (Ho:YAG) laser to decompress ureterocele (UC) in pediatric population, and only two studies compared its outcomes with electrosurgery. This study aims to compare outcomes of Ho:YAG laser transurethral endoscopic puncture (TUP) versus electrosurgery TUP of UC in the 1 month of life, analyzing incidence of secondary surgery, redo TUP, and iatrogenic vesicoureteral reflux (VUR).

Patients And Methods: A retrospective study of patients treated by TUP of UC from 2008 to 2017 was performed. Read More

Giant hydronephrosis is defined as an extensive dilation of the pyelocaliceal cavities occupying a large part of the abdominal cavity or as a dilation filled up with more than a liter of urine overflowing the median line. This is due, more often, to pyelo-ureteral junction syndrome. Obstruction due to ureterocele complicated by lithiasis is a very rare cause of giant hydronephrosis. Read More

Congenital anomalies of the kidneys or lower urinary tract (CAKUT) are the most common causes of renal failure in children and account for 25% of end-stage renal disease in adults. The spectrum of anomalies includes renal agenesis; hypoplasia; dysplasia; supernumerary, ectopic or fused kidneys; duplication; ureteropelvic junction obstruction; primary megaureter or ureterovesical junction obstruction; vesicoureteral reflux; ureterocele; and posterior urethral valves. CAKUT originates from developmental defects and can occur in isolation or as part of other syndromes. Read More

Background: Spinal anesthesia (SA) is an established anesthetic technique for short outpatient pediatric urological cases. To avoid general anesthesia (GA) and expand regional anesthetics to longer and more complex pediatric surgeries, the authors began a program using a combined spinal/caudal catheter (SCC) technique.

Study Design: The authors retrospectively reviewed the charts of all patients scheduled for surgery under SCC between December 2016 and April 2018 and recorded age, gender, diagnosis, procedure, conversion to GA/airway intervention, operative time, neuraxial and intravenous medications administered, complications, and outcomes.

Suprapubic grasper-assisted transvesical endoscopic ureterocele puncture: a novel technical innovation.

J Pediatr Urol 2019 May 13;15(3):274-276. Epub 2019 Apr 13.

Consultant Pediatric Surgeon, Department of Pediatric Surgery and Pediatric Urology, Latifa Women and Children Hospital, Dubai, United Arab Emirates.

Although endoscopic drainage remains treatment of choice for ureterocele in pediatric age group, often urologists, especially during the learning phase and difficult anatomy, feel a limitation because of inability to do intravesical manipulation. This can be attributed to absence of the second working channel in pediatric cystoscope owing to size limitation. Herein, we describe a novel technique for safe introduction of a grasper which acts as a second surgical arm for endoscopists and simultaneously facilitates both intravesical manipulation and drainage of ureterocele at an optimal location with minimal complications.

Department of Paediatric Surgery and Urology, Birmingham Children's Hospital, Steelhouse Lane, Birmingham, B4 6NH, United Kingdom. Electronic address:

Introduction: Renal agenesis and multicystic dysplastic kidney (MCDK) are usually associated with either an absent or atretic ureter. Occasionally, these renal anomalies may be associated with a dilated tortuous ureter, ureterocele or other cystic malformation of mesonephric duct (MND) remnants.

Objectives: The objective of this study was to identify and classify anatomical variants of tubulocystic remnants of the MND, with a secondary focus on natural history and management outcomes. Read More

Robotic surgery in pediatric urology: Current status.

Asian J Endosc Surg 2018 Nov 27;11(4):308-317. Epub 2018 Sep 27.

Department of Pediatric Urology, Nagoya City University Graduate School of Medical Sciences, Nagoya, Japan.

Robot-assisted laparoscopic surgery (RALS) has been increasingly embraced in the fields of adult and pediatric urology, especially in North America and Europe. The advantages of a stable magnified 3-D view, tremor filtering, and motion scaling allow for precise intracorporeal exposure and suturing. Because most surgeries are performed as reconstructive rather than excision procedures, the robotic platform is particularly feasible for the field of pediatric urology. Read More

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.
