The aim of the present systematic review was to evaluate the evidence of a potential learning curve for laser treatment of benign prostatic hyperplasia.
A systematic literature search was conducted in November 2011 using The Cochrane Library, EMBASE and MEDLINE. Overall, 18 sources (mostly case series) were included for further assessment. The majority of publications assume that a general learning curve exists. It is estimated that a range of 20 to 50 cases is needed to achieve a stable outcome level. For the most part, these findings are based on the HoLEP (Holmium laser enucleation of prostate) technique and intraoperative measures, such as enucleation efficiency. Valid conclusions regarding patient-related end-points are difficult to make, although some studies report a decreasing trend for complication rates with increasing experience of the surgeon. No statistically significant differences were found for postoperative outcomes such as IPSS (International Prostate Symptom Score), Qmax (peak flow rate) or Quality of Life. Overall, the present results are highly limited by the low evidence level and methodological problems of the publications available. Several publications suggest that adequate training during the implementation phase is relevant.
