A Case-control Study To Compare The Outcomes Between Transurethral Vapor Enucleation And Resection Of The Prostate And TURP

Objective:To assess and compare the perioperative,short-term functional outcomes of treating low urinary tract symptoms(LUTS)secondary to benign prostate hyperplasia(BPH)between transurethral vapor enucleation and resection of the prostate(TVERP)and transurethral resection of the prostate(TURP).Materials and Methods:A retrospective review of patients treated for BPH,from January 2016 to December 2016,was performed by using electronic medical records system of our hospital.Patients who underwent TVERP or TURP were included in the study.The perioperative clinical features of the two groups such as age,prostate volume(PV),post-void residual(PVR),prostate specific antigen(PSA),hemoglobin(HGB),International Prostate Symptom Score(IPSS),quality of life(QoL),Operating time,resected weight of the prostate,bladder irrigation time,catheterization time,hospital stay were collected and analyzed.Complications were recorded and the routine follow-up of the patients were conducted at 1,3,6,12,24 months afterwards.Results:249 patients with BPH were included in the study.TVERP was performed in 92 patients and TURP was performed in 157 patients.The preoperative indicators of the two groups were comparable.A significantly less HGB loss and bladder irrigation duration were observed in the TVERP group(7.3 ± 9.7 g/1 and 2.2±0.7 days,respectively)than in the TURF group(14.0 ±11.9g/1 and 2.6 ± 1.6 days,respectively,p<0.05).In the TURP group,the mean operating time was shorter than the TVERP group obviously(71.4±21.6 min vs 119.9±73.1 min,p<0.05).Follow-up at 1,3,6,12,24 months after operation,there were significant reductions in IPSS(45.4%,56.8%,64.3%,68.3%and 67.8%in TVERP vs 47.5%,57.9%,64.7%,69.2%and 68.8%in TURP)and QoL(40.1%,52.7%,60.3%,67.1%and 59.5%in TVERP vs 40.8%,53.7%,60.6%,67.2%and 58.9%in TURP).Subjective urine flow parameters of the two group were comparable at different follow-up points.With respect to early and late complications,there was no significant difference between the two groups(p>0.05).Conclusions:According to the study,the effect and safety of TVERP and TURP seem to be equal.However,compared with TURP,the hyperplastic tissue of prostate can be resected more thoroughly by TVERP.And the specific characteristics including a better effect of hemostasis,as well as a blood-free operative view may make TVERP become a good choice on treating BPH.
