[Transurethral plasma resection of the prostate for acute urinary retention in patients with advanced prostate cancer].

ABSTRACT

OBJECTIVE: To compare the safety of transurethral plasma resection of the prostate (TuPkRP) in the treatment of advanced PCa (APC)-related acute urinary retention (AUR) with that in the treatment of BPH-related AUR and investigate the oncologic characteristics of the PCa patient after TuPkRP. METHODS: In this retrospective study, we first compared the baseline data between the patients with APC-related AUR (group A, n = 32) and those with BPH-related AUR (group B, n = 45) as well as their surgical parameters, such as the operation time, pre- and post-operative hemoglobin levels, IPSS at 3 months after TuPkRP and length of postoperative hospital stay. Then, we observed possible TuPkRP-induced tumor progression by comparing the oncologic parameters, such as the PSA level and ECT-manifested bone metastasis, between the APC-AUR patients treated by androgen-deprivation therapy (ADT) + TuPkRP and those treated by ADT only (group C, n = 24). RESULTS: There were no statistically significant differences in the baseline data between the APC-AUR and BPH-AUR patients (P > 0.05). The operation time and postoperative hospital stay were significantly longer in the APC-AUR than in the BPH-AUR group (P < 0.05), but the decreases in the hemoglobin level and IPSS at 3 months after operation showed no significant differences between the two groups of patients (P > 0.05). Besides, no statistically significant differences were observed in the oncologic parameters between the APC-AUR patients treated by ADT + TuPkRP and those by ADT only (P > 0.05). CONCLUSION: The safety of TuPkRP was not significantly lower and the rates of postoperative complications and adverse events were not significantly higher in the patients with APC-related AUR than in those with BPH-related AUR. And this surgical strategy did not significantly improve the progression of APC.
