title: The use of a multipurpose stent in children.
abstract: OBJECTIVE
  To assess the use of a multipurpose stent (the 'Blue stent', Angiomed Urosoft Pyeloplasty Stent, Bard, UK) in children undergoing pyeloplasty and ureteric reimplantation.
  
  
  METHODS
  Between August 1994 and August 1996, the Blue stent was used in 50 renal units in 46 children aged 2 months to 12 years and 6 months. Twenty-five children underwent pyeloplasty, 11 had ureteric reimplantation for vesico-ureteric reflux (VUR), eight had ureteric reimplantation with remodelling for obstructed megaureters and in two patients it was used during the removal of stones. The mean follow-up was 18 months (range 6-30 months).
  
  
  RESULTS
  After pyeloplasty, 22 patients (88%) had improved renal function and drainage with a decrease in hydronephrosis; two patients had a decrease in hydronephrosis only, one had an anastomotic leak and needed a repeat pyeloplasty and four developed a urinary tract infection (UTI). After ureteric reimplantation, VUR was not detected in any patient. Two patients had no change in drainage after remodelling and reimplantation of a megaureter, one was later diagnosed as having a neuropathic bladder and one child developed a UTI after ureteric reimplantation. The hospital stay was 3 days after pyeloplasty and 5 days after reimplantation.
  
  
  CONCLUSIONS
  The design of the multipurpose Blue stent provides versatility; it can be used as a stent, and both an internal and external drain. Its use does not prolong the hospital stay. Insertion causes minimal trauma to the renal parenchyma, and removal is easy, pain-free and requires no anaesthesia. The complication rates in the present series compare favourably with other reported series.
