Surgical plane positioning with a disposable circumcision suture device for the treatment of phimosis and redundant prepuce / 中华男科学杂志

<p><b>Objective</b>To investigate the clinical effects of circumcision by surgical plane positioning with a disposable circumcision suture device in the treatment of phimosis and redundant prepuce.</p><p><b>METHODS</b>From September 2016 to June 2017, we treated 250 patients with phimosis or redundant prepuce, 127 by conventional circumcision (the control group) and the other 123 by surgical plane positioning with a disposable circumcision suture device (the observation group). We compared the operation time, intra-operative bleeding, preputial frenulum alignment, postoperative ecchymosis, and postoperative penile appearance between the two groups of patients.</p><p><b>RESULTS</b>Compared with the controls, the patients in the observation group showed significantly longer operation time (［4.48 ± 1.18］ vs ［7.17 ± 1.42］ min, P<0.05), lower rates of intra-operative frenulum bleeding (15.0% ［19/127］ vs 4.1% ［5/123］, P<0.05) and frenulum misalignment (26.8% ［34/127］ vs 0.8% ［1/123］, P<0.05), higher incidence of postoperative ecchymosis (41.7% ［53/127］ vs 21.1% ［26/123］, P<0.05), and higher satisfaction of the patients with the postoperative penile appearance (92.9% ［18/127］ vs 98.4% ［121/123］, P<0.05). However, no statistically significant difference was found between the control and observation groups in intra-operative non-frenulum bleeding (4.7% ［6/127］ vs 1.6% ［2/123］, P = 0.164).</p><p><b>CONCLUSIONS</b>Circumcision by surgical plane positioning with a disposable circumcision suture device can effectively avoid preputial frenulum misalignment, reduce intra-operative bleeding, and improve postoperative penile appearance.</p>

Androgen deprivation therapy for prostate cancer: a follow-up study of the patients' survival time / 中华男科学杂志

<p><b>OBJECTIVE</b>To explore the long-term survival and prognosis of prostate cancer patients after treated by androgen deprivation therapy.</p><p><b>METHODS</b>We conducted a follow-up study of 124 patients with prostate cancer treated by androgen deprivation therapy, and compared the survival times of the patients with different pathological grades and clinical characteristics using Kaplan-Meiers survival curves.</p><p><b>RESULTS</b>The mean survival time of the 124 patients after androgen deprivation therapy was 5. 912 years, with the median survival time of 7.81 years. The patients with bone metastases showed a shorter survival time than those with non-bone metastasis (P = 0.04). Pathological grades and PSA levels were not prognostic factors. No significant differences were found in the mean survival time between those died of prostate cancer (n = 35) and those from other factors (n = 23) (P = 0.50).</p><p><b>CONCLUSION</b>Bone metastasis is an important prognostic factor in advanced prostate cancer following androgen deprivation therapy, which is more significantly correlated with the survival time of the patients than tumor grades and clinical classification.</p>
