Purpose
To compare the perioperative and postoperative outcomes between Oyster prostate vaporesection using Tm−YAG laser and the conventional transurethral prostatectomy using monopolar energy.
Methods
Patients with LUTS with an accumulative size of at least 60 ml were randomly assigned to one of two parallel groups to undergo Tm-YAG laser vaporesection (Group 1) or conventional monopolar transurethral prostatectomy (Group 2). The primary endpoints were the reduction in IPSS and the increase in Qmax postoperatively. Secondary endpoints included the Hemoglobin drop, the complication rate, the changes in urodynamic parameters, the duration of hospitalization and catheterization and the changes in IIEF during the 24-month follow-up.
Results
In total 32 and 30 patients were enrolled in Groups 1 and 2, respectively. Patient age (p = 0.422) and prostate volume were similar among the groups (p = 0.51). The outcomes in terms of IPSS decrease and Qmax amelioration were comparable (p = 0.449 and p = 0.237, respectively). Operative and hospitalization times were lower in Group 1 (p = 0.002 and p = 0.004, respectively). Hemoglobin drop, changes in urodynamic parameters and improvement in IIEF and QoL scores did not differ among the two Groups. The average time with the catheter was 2.06 ± 0.35 and 2.5 ± 0.82 (p = 0.003) days for Group 1 and Group 2, respectively. The overall complication rate was 6.2% for Group 1 and 13.3% for Group 2.
Conclusions
The Oyster technique leads to similar postoperative outcomes compared to the standard monopolar transurethral prostatectomy. The shorter catheterization, hospitalization and operation time should be considered advantages of the Oyster technique.
