66 29 th CONGRESS OF THE ESPU transanastomotic diversions (p=0.002) and children without pre-operative diversion (p=0.005). The analysis of patients in chronological order revealed an increase in prenatal diagnosis in the recent years (p<0.001). Recurrence and complications were not found to be related with age, gender, side, hydronephrosis grade, surgery type and surgical findings. CONCLUSIONS Surgical treatment of UPJ obstruction is satisfactory in any age and hydronephrosis grade. Recurrences are closely related to the presence of early postoperative complication and diver- sion type. Placing temporarily preoperative diversions (either internal or external) should not be encouraged since the postoperative complications and recurrences develop more. However, use of transanastomotic diversions are advantageous in terms of complications. 10:00–10:03 S6-6 (PP) MANAGEMENT OF HYDRONEPHROSIS WITH LESS THAN 10 % FUNCTION Rachida LAAMIRI, Nahla KECHICHE, Lasaad SAHNOUN, Mongi MEKKI, Mohsen BELGUITH and Abdelatif NOURI Fattouma Bourguiba University Hospital, Pediatric surgery, Monastir, TUNISIA PURPOSE To determine the efficacy and long-term outcome of pyeloplasty in poorly functioning kidneys (less than 10 %) in the pediatric age group. MATERIAL AND METHODS We retrospectively analyzed data from 17 infants (15 male, 2 female) with prenatally or postna- tally diagnosed hydronephrosis due to UPJO treated by Anderson-Hynes pyeloplasty (AHP) in our hospital over 14 years. The length of postoperative followup was 26 months on average (range 3–80 months) RESULTS In 3 patients, percutaneous nephrostomy (PCN) was performed, followed by AHP. 14 patients underwent AHP without preceding PCN. DTPA renograms were done post pyeloplasty period in 10 patients (after 1 year). In 9 patients, split function increased from < 10 % preoperatively to 21,33 % (range 9 to 41 %) postoperatively. Of all patients, only one had significant deterioration in split function and underwent nephrectomy. No complications were noted after pyeloplasty in the 16 over cases. CONCLUSIONS Pyeloplasty gives good results in poorly functioning kidneys in the pediatric age group, and in most cases the sacrifice of such kidneys can be avoided. 1 year).
