Background:This study was designed to review the long-term results and complications of the two techniques of retrograde endopyelotomy; ureteroscopic holmium laser endopyelotomy versus Acucise endopyelotomy. The results were then compared with the laparoscopic pyeloplasty results from a recent publication.Patients and methods: The study was conducted retrospectively from January 2004 to July 2007. Seventy-two patients with ureteropelvic junction obstruction (UPJO) underwent retrograde endopyelotomy using either ureteroscopic laser endoincision (42 patients) or fluoroscopic guided hot-wire balloon (Acucise) endoincision (30 patients). Preoperative radiological assessment included intravenous pyelogram (IVP), helical computerized tomography and diuretic renography. The follow-up period ranged from 12 to 42 months. Subjective success was guided by the change in the preoperative flank pain while objective success on radiological evaluation was documented by either nonobstructed curve of diuretic renogram and/or T1/2 less than 10 min.Results: The mean patient age was 42.6±7.5 years for the laser group and 39.2±15.1 years for the Acucise group (p = 0.24). The operative time was 66.8±22.2 min in the laser group and 59.8±20.3 min in the Acucise group (p = 0.84). By objective standards (renal scan), a total of 56 (77.8%) cases were successful (nonobstructed curve). This number included 34 cases in the laser group (80.9%) and 22 cases in the Acucise group (73.3%) (p = 0.2). Overall 16 failure cases were evident clinically within 1 year of the procedure (eight cases in each group). Most of the failure cases (13/16) presented with clinical obstructive symptoms during the early follow-up period (within 3 months postoperatively) and were then confirmed radiologically (six cases in the laser group and seven cases in the Acucise group) while only three patients had failures at 6, 9 and 11 months postoperatively. There was no statistically significant difference as regards intra-operative complications between the two groups (p = 0.4). Intra-operative bleeding was seen in three cases in the Acucise group while postoperatively it was reported in one case.Conclusion: The retrograde endopyelotomy approach is safe and effective for the treatment of patients with UPJO. Both ureteroscopic laser and the hot-wire balloon (Acucise) techniques have an important role in the management of UPJO, especially in secondary cases, and they provide comparable long-term objective and subjective outcomes. Laparoscopic pyeloplasty provides far better results but with higher costs, and requires well-equipped centers and involves a long learning curve. [ABSTRACT FROM PUBLISHER] |
