During the last few years, prostate cancer is more frequently diagnosed in young patients. This lays emphasis on the necessity to preoperatively evaluate the sexual function in patients undergoing bilateral nerve sparing radical retropubic prostatectomy (BNSRRP). The aim of our study was to make an objective evaluation of the basic sexual function in patients with clinically localized prostate cancer and candidates for BNSRRP, using internationally validated questionnaires. We also tried to find a correlation between these questionnaires and the individual assessment of candidates, on one hand, and between comorbidities of the patients and degree of erectile dysfunction (ED), on the other hand. From January 2014 to March 2017, at the urology clinic of University Hospital – Pleven, 64 patients opted BNSRRP and reported to have preserved erectile function (EF), wishing to maintain this function after surgery. The patients’ histories and comorbidities were recorded on the day of hospitalization. The subjective assessment of the patients’ potency was compared with International Index of Erectile Function (IIEF). According to the EF domain of the IIEF, baseline EF was assessed in 28 patients. Twelve patients had mild ED, 9 patients had mild to moderate ED, seven patients had moderate, and eight had severe ED. The results showed that a significant number of patients with clinically localized prostate cancer who were candidates for BNSRRP reported to be fully potent but actually had impaired EF preoperatively. There was also a pronounced correlation between concomitant diseases and EF.

The experience accumulated with low-intensity extracorporeal shock wave therapy (LI-ESWT) from international clinical trials has demonstrated its safety, efficacy and good tolerance in treatment of erectile dysfunction (ED). The aim of this retrospective study was to investigate the effect of LI-ESWT in patients with ED after bilateral nerve sparing radical surgery for prostate cancer. Twenty-seven patients underwent bilateral nerve sparing radical retropubic prostatectomy (BNSRRP) at the clinic of urology of the university hospital in Pleven between January 2016 and December 2016. Twenty-one of these patients had pre-operative preserved erectile function (EF), as reported according to the International Index of Erectile Function (IIEF-5). Postoperatively, these 21 patients experienced a mild (18-21 points) impairment of EF. In 10 patients (group 1), LI-ESWT was performed. The procedure was performed once a week for 6 weeks with a LI-ESWT (BTL 6000 SWT Topline) instrument. The reading was obtained with IIEF-5 on the third and sixth month after the end of therapy. The other 11 patients (group 2) were used as a control group and did not receive treatment. In 5 patients in group 1, a recovery of EF (> 21 points) as per IIEF-5 was recorded at the third month after treatment. In two patients, the same score was recorded at the sixth month. No improvement was seen in three men in group 1. In the controls (group 2), a spontaneous EF improvement in four patients at sixth month was registered. Despite the small number of patients and their short-term follow-up, our initial results indicate that LI-ESWT is effective, safe and well-tolerated. It could be an alternative for early penis rehabilitation in patients who have undergone BNSRRP.
