The estimated recurrence rate of benign prostatic hyperplasia (BPH) after transurethral resection of the prostate is about 5 to 15%. Laser enucleation of the prostate results in a much lower recurrence rate (not exceeding 1-1. 5%). At the same time, laser enucleation of the prostate is still not widely used for recurrent prostatic hyperplasia since it believed to be technically difficult in cases.
To describe the distinctive features of thulium and holmium laser enucleations of the prostate in the management of recurrent BPH and show that the technical difficulties are not an obstacle to the wide application of this technique.
This was a retrospective study comprising 676 patients aged 54 to 87 years with clinically pronounced infravesical obstruction due to prostatic hyperplasia (IPSS>20, Qmax<10). All patients were divided into four groups. Groups 1 (n=489) and 3 (n=153) underwent holmium (HoLEP) and thulium (ThuLEP) laser enucleations of the prostate, respectively. Groups 2 (n=23) and 4 (n=11) included patients with BPH recurrence after HoLEP (group 2) and ThuLEP (group 4). All patients underwent diagnostic evaluation at baseline and at 6 months after surgery.
The mean ThuLEP operating time was shorter than that of HoLEP (p=0.02). The mean duration of repeat and primary ThuLEP and HoLEP did not differ statistically significantly (p>0.05). There was no difference in the length of hospitalization and catheterization between the four groups (p>0.05). At six months after surgery, a statistically significant improvement in I-PSS, Qmax, QoL, and RUV was observed in all groups compared with preoperative values (p>0.05)).
We found that the technical difficulties of the re-operation, such as the difficult separation of adenomatous tissue from the prostate capsule, the multinodular nature of the adenoma, increased tissue density are easy to overcome and do not confer a significant complexity. In turn, better completeness of resection, low complication and recurrence rates and the possibility of surgery, even in elderly patients with multiple comorbidities - these features allow us to conclude that laser enucleation of the prostate is not only an effective treatment for infravesical obstruction due to benign prostatic hyperplasia, but is also a method of choice in the treatment of patients with recurrent BPH.
