Abstract In this study an experimental device for testing the structural integrity of lower limb (transtibial and transfemoral) prostheses is proposed and studied, in accordance with the ISO 10328 Standard. Aim of the development of this device is to mechanically test these kinds of prostheses, for claiming the compliance with the standard. In the first part of the paper, experimental setup of the laboratory is described for the different kinds of prescribed tests. In the second part, the test case of a transtibial prosthesis for children is proposed. After verifying the compliance with the standard of More >

Abstract Umbilical laparoendoscopic single-site surgery (U-LESS) is a relatively new technique for minimally invasive surgery being implemented in patients with urological complaints. We report the case of an incontinent 8-year-old girl who successfully underwent U-LESS for nephrectomy of a minimally functioning kidney with ectopic ureteral insertion into the vagina. More >

Abstract Introduction: Pediatric urolithiasis is relatively uncommon and limited information is available on the application of minimally invasive management modalities in young children. We present a single centre experience with extracorporeal shockwave lithotripsy (ESWL) for infants with upper urinary tract calculi.
Material and methods: A total of 74 infants aged 3 months to 24 months with upper urinary tract calculi were treated with ESWL under general anesthesia using the Wolf 2500 and the 2501 Piezolith lithotriptors over a 14 and a half-year period. Patient and stone characteristics, risk factors for urolithiasis, treatment parameters, clinical outcomes and long-term follow-up… More >

Abstract Pediatric renal cell carcinoma (RCC) is relatively rare and appears to comprise a group of tumors distinct from RCCs typically seen in adults. Recently described tumors show an association with neuroblastoma or specific chromosomal translocations. Only rarely have other childhood cancers been associated with pediatric RCC. We present two cases of pediatric RCC following treatment of other childhood malignancies not previously described, supratentorial primitive neuroectodermal tumor and acute lymphoblastic leukemia, and review the literature on pediatric RCC. As the RCCs were discovered as incidental radiologic findings, we emphasize the importance of close follow-up (including imaging) More >

Abstract Introduction: Endoscopic techniques are becoming increasingly accepted for treatment of vesicoureteric reflux as alternatives to open surgical reimplantation. However, there is some debate about the ideal injectable material. Since we have accumulated experience with several substances, an opportunity existed to compare them.
Materials and methods: From 1991 to 2003, 101 children with vesicoureteric reflux were treated by endoscopic subureteric injection either once (74) or twice (27) by either of two pediatric urologists. There were a total of 165 ureteral injections, 83 with polytetrafluoroethylene (Teflon®), 73 with polydimethylsiloxane (Macroplastique®), and 9 with collagen. Each child was evaluated pre-operatively… More >

Abstract Xanthogranulomatous pyelonephritis (XGP) is a rare, chronic inflammatory lesion of the kidney associated with both chronic infection and obstruction. Most common in middle-aged females, it is important to recognize in children because it may be confused with childhood renal malignancies particularly Wilms’ tumor. We report a case of a 1-year old male with antenatally detected and postnatally confirmed hydronephrosis. Further investigation revealed a left incomplete duplex collecting system with obstructing lower pole stones, pelvicaliectasis and widespread foci of calcification. He underwent a left nephroureterectomy with the pathological report noting XGP. More >

Abstract Introduction: Management of vesical calculi in children poses an interesting challenge to the urologist. The treatment options currently available include open surgery, transurethral pneumatic cystolithotripsy, percutaneous suprapubic cystolithotomy and shockwave lithotripsy (SWL). Holmium:YAG (Ho:YAG) laser cystolithotripsy represents a novel modality of treatment that is minimally invasive.
Materials and methods: From July 1999 to January 2003 we treated 23 children with vesical calculi using transurethral Ho:YAG laser lithotripsy. The indications for cystolithotripsy were stone size ≤4 cm (N=19), or multiple stones with combined stone burden ≤4 cm (N=4). The mean patient age was 7.8 (range 2-12) years and… More >

Abstract Background: Wilms' Tumor is the most common malignant neoplasm of the urinary tract in children. Since 1969, the National Wilms' Tumor Study Group (NWTSG) has contributed to improving the clinical management and outcome of children affected by Wilms' Tumor. We have managed our patients according to NWTSG protocols and report our results herein.
Methods: Retrospective chart review of consecutive patients presenting at the Children's Hospital of Eastern Ontario (CHEO) with a diagnosis of Wilms' Tumor between April 1990 and March 2001.
Results: Forty patients with Wilms' Tumor (18 M/22 F) were diagnosed at CHEO during this interval. Mean… More >

Abstract Prune Belly Syndrome developed urinary ascites secondary to forniceal rupture. Treatment consisted of bilateral cutaneous pyelostomies. Even though most children with Prune Belly Syndrome respond to lower urinary tract drainage, a cutaneous pyelostomy may be necessary when the ureters are tortuous and do not drain adequately following bladder decompression.

Abstract Purpose: Extracorporeal shock wave lithotripsy (ESWL) in older children appears to have comparable results when compared to adults, no study has focused on its use in younger children. We reviewed our ESWL experience in children under age 3.5 years to evaluate its safety, and define optimal treatment parameters.
Methods: We retrospectively reviewed consecutive medical and diagnostic imaging records from three ESWL centers, pertaining to 34 children under 3.5 years of age (36 renal units-RU). The children were from two distinct populations served exclusively by the three centers. We analyzed patient presentation, etiology, age, weight, stone size, preoperative… More >
