World J Clin Cases 2019 May;7(10):1169-1176

Department of Pediatrics, PLA General Hospital, Beijing 100853, China.

Background: Renal duplication is a common deformity of the urinary system, with an incidence of approximately 1/125 in children. Symptomatic patients with hydronephrosis, vesicoureteral reflux, or incontinence may require surgical interventions. Laparoscopy and retroperitoneoscopy are the two main accesses for partial nephrectomy. Read More

What's the best minimal invasive approach to pediatric nephrectomy and heminephrectomy: conventional laparoscopy (CL), single-site (LESS) or robotics (RAS)?

Transl Pediatr 2016 Oct;5(4):240-244

Department of Paediatric and Adolescent Surgery, Medical University of Graz, Graz, Austria.

Background: Conventional laparoscopy (CL) using 3-5 mm ports has become the goldstandard for pediatric nephrectomy (N), heminephrectomy (HN) and heminephrecto-ureterectomy (HNU) for many years now. Recently the spectrum of minimal invasive surgery (MIS) has been extended by variants like laparoendoscopic single-site surgery (LESS) or robot-assisted surgery (RAS). However such technical developments tend to drive surgical euphoria and feasibility studies, but may miss adequate academic research about function and proven patients' benefits. Read More

Evaluation and outcome of the distal ureteral stump after nephro-ureterectomy in children. A comparison between laparoscopy and retroperitoneoscopy.

J Pediatr Urol 2016 Apr 14;12(2):119.e1-8. Epub 2015 Nov 14.

Department of Translational Medical Sciences, Federico II University of Naples, Naples, Italy.

Background: In children with a poorly functioning kidney due to vesicoureteral reflux (VUR) or ureteropelvic junction obstruction, management is by nephrectomy with total or proximal ureterectomy. The complete removal of all the ureter minimizes the risk of future morbidity associated with the distal ureteral stump (DUS), including febrile urinary tract infections (UTIs), lower quadrant pain and hematuria, the so-called ureteral stump syndrome.

Objective: To assess the outcome of the DUS after nephroureterectomy, we analyzed our recent experience of nephrectomy performed via retroperitoneoscopy and via laparoscopy. Read More

[Treatment of upper urinary tract tumors. Report of our experience].

Arch Esp Urol 2004 Apr;57(3):189-97

Servicio de Urología, Hospital Ramón y Cajal, Madrid, España.

Objectives: The objective of this article is to perform a comprehensive exposition of the various non-endourological treatment options for upper urinary tract tumors in order to set the bases to choose the most adequate surgical indication depending on tumors' and patients' characteristics; we consider the various surgical approaches, and the historic evolution from the classic indication established by Albarran (radical nephroureterectomy with bladder cuff) to the current ones more conservative. We also consider the role of radiotherapy and chemotherapy in the treatment of these tumors.

Methods/results: We refer to the conclusions of various authors and their large series published in the literature, series considered classic already, and provide support adding our experience by reviewing 223 patients treated from 1977 to 2003 with a mean follow-up of 45 months (maximum 238 months).

[One-stage laparoscopic bilateral upper pole nephrectomy for ectopic insertion of complete ureteral duplication].

Prog Urol 2003 Apr;13(2):342-5

Service d'Urologie-Andrologie, Hôpital Nord, 42055 Saint Etienne.

Ectopic ureteric insertion of the superior renal unit in the context of complete ureteric duplication is frequently accompanied by destruction of the corresponding parenchymal territory. Surgical treatment must comprise upper pole nephrectomy with partial ureterectomy. The authors report a case of one-stage retroperitoneal laparoscopic bilateral treatment which could become the treatment of choice of this disease. Read More

The role of refluxing distal ureteral stumps after nephrectomy.

J Pediatr Surg 2002 Apr;37(4):653-6

Instituto de Urologia e Nefrologia, São José do Rio Preto, São Paulo, Brazil.

Background/purpose: Classically, the refluxing distal ureteral stump has been removed during the nephrectomy by the means of an incision on the flank and lower abdominal wall. There are little data in the literature about the natural history of these stumps. In the current work the authors evaluated possible complications affecting the ureteral stump after total or partial nephrectomy for vesicoureteral reflux. Read More

Department of Urology, Uji Tokushukai Hospital, Kyoto, Japan.

Coexistence of congenital ureteral diverticulum and hydronephrosis caused by vascular compression is a rare entity. The authors experienced a case of congenital ureteral diverticulum coexistent with hydronephrosis caused by aberrant vascular compression by uterine and umbilical arteries in a 14-year-old girl. The authors could not diagnose accurately this abnormality preoperatively by 3-dimensional computed tomography. Read More

Pediatrie 1993 ;48(9):645-8

Service de chirurgie pédiatrique, CHU Nord, Marseille, France.

The authors report on two cases of renal cell carcinoma in boys of 8 and 13 years of age revealed by gross hematuria. Following nephrectomy the evolution remains good after 8 and 17 years of follow-up. Despite the fact that renal cell carcinoma is rare in children, it must be evoked as a possible etiology in the presence of spontaneous and relapsing hematuria in a child older than 8 years of age.

[Endoscopic ureterectomy].

Arch Esp Urol 1991 Jun;44(5):573-7

Servicio del Urología, Hospital Clínico Universitario de Zaragoza, España.

Endoscopic ureterectomy is a minimally invasive surgical technique indicated in cases warranting ureterectomy to complement extended nephrectomy for pyelocaliceal urothelial carcinoma. The results achieved are identical to those of conventional ureterectomy (open surgery) without the inconvenience or sequelae that usually present with the latter procedure. In 1982, the authors developed the modified Dell'Adami and Breda endoscopic ureterectomy technique. Read More
