ABSTRACT
INTRODUCTION:
Morcellation of intravesical adenoma (MIA) is an important part of the endoscopic enucleation procedure. The aim of this study was to analyse the learning curve of the MIA during endoscopic enucleation of the prostate.MATERIAL:
We conducted a prospective study of the first 90 patients treated by endoscopic enucleation of the prostate by a single surgeon without previous experience of MIA. The population was divided into 3 consecutive groups of 30 patients. MIA was performed with the morcellator Pinranha (Wolf) and disposable blades (Vmax©). The criteria selected to assess the progress of MIA over time were duration of MIA (min), the intraoperative complications encountered during MIA and weight morcelleted tissue. The efficacy of MIA was assessed with the ratio weight specimen/MIA duration (min/g) over time.RESULTS:
The three groups were comparable in terms of age, ASA score of prostate volume. A significant decrease in the duration of MIA was found between groups 1 and 2 (12 versus 5.5min, P<0.0001), to reach a plateau in the group 3 (3min). A significant increase in the efficiency of MIA was found between group 1 and 2 (5.5 versus 11g/min, P<0.0001), to reach a plateau in the group 3 (20g/min). Bladder injuries were limited (7.7%), superficial and encountered in the early learning phase.CONCLUSION:
In our experience, the MIA required a learning curve estimated between 30 and 60 procedures. LEVEL OF EVIDENCE IV.Palabras clave
