Enterocystoplasty vs detrusorectomy: outcome in the adult with spina bifida.

PURPOSE: Bladder augmentation by enterocystoplasty or detrusorectomy might prevent renal damage, help achieve dryness and decrease the need for antimuscarinics. We compared the long-term outcomes of enterocystoplasty and detrusorectomy in adults with spina bifida. MATERIALS AND METHODS: A retrospective study using the hospital electronic database was performed. We identified 47 patients with spina bifida (median age at followup 26.8 years) who underwent either enterocystoplasty or detrusorectomy between 1988 and 2004. Median followup was 13.1 years in the detrusorectomy group and 15.3 years in the enterocystoplasty group. RESULTS: In the detrusorectomy group 4 patients with treatment failure were identified. All 4 patients underwent secondary enterocystoplasty. No reoperation was necessary in the enterocystoplasty group. Preoperative bladder volume was approximately 100 ml higher in the detrusorectomy group (not significant). There was a significantly greater improvement of median bladder volume in the enterocystoplasty group (increase of 300 vs 77.5 ml, p = 0.006). No differences in continence rate, antimuscarinic use or condition of the upper tract were found. CONCLUSIONS: In this series of 47 patients long-term outcomes were good after enterocystoplasty and detrusorectomy, although bladder volume exhibited a greater increase in the enterocystoplasty group. No differences were observed among the other outcomes. If preoperative bladder volume is sufficient, detrusorectomy can be considered before enterocystoplasty is done.

The use of endoluminal ultrasonography for preventing significant bleeding during endopyelotomy: evaluation of helical computed tomography vs endoluminal ultrasonography for detecting crossing vessels.

OBJECTIVE: To evaluate, in a prospective study, the efficiency of helical computed tomography (CT) and endoluminal ultrasonography (ELUS) for detecting significant crossing vessels, a major cause of bleeding complications when treating patients with pelvi-ureteric junction (PUJ) obstruction, and to compare our results using ELUS with those of an earlier multicentre study (not using ELUS), to see whether the complication rate decreased. PATIENTS AND METHODS: The study included 27 patients with a PUJ who had isotope renography, intravenous urography, helical CT and ELUS before surgery. Depending on the findings of ELUS, patients were treated with a pure lateral Acucise incision (Applied Medical, Irvine, CA, USA) an Acucise with changed cutting direction, or (later) a laparoscopic pyeloplasty. RESULTS: ELUS detected 15% more crossing vessels than helical CT; 16 patients had Acucise (seven lateral, nine other cutting direction), eight were treated with a laparoscopic pyeloplasty and three with other procedures. By contrast with earlier reports and as a consequence of using ELUS, there was no bleeding, vs 16% in the study not using ELUS. The success rate of 73% of the endourological approach is comparable with previous reports. CONCLUSION: ELUS is more sensitive in detecting relevant crossing vessels than helical CT and therefore the use of ELUS can better prevent bleeding complications. ELUS can also improve the success rate by helping in selecting the correct treatment. Because it is minimally invasive and safe, ELUS combined with Acucise (or other possible endourological techniques, like holmium laser incision) should be the first choice of treatment for PUJ stenosis.
