Real-time transrectal ultrasonography in seminal vesiculoscopy / 中华男科学杂志

Objective@#To compare three different pathways for transurethral seminal vesiculoscopy (SVS) and investigate the reliability and efficiency of transrectal ultrasonography (TRUS)-guided SVS (TRUS-SVS).@*METHODS@#We retrospectively analyzed 90 cases of seminal vesiculoscopy conducted directly through the ejaculatory duct or prostatic utricle or under the guide of TRUS. We compared the success rate and complications among the three approaches.@*RESULTS@#Operations were successfully performed in 87 (96.67%) of the 90 cases, 30 through the ejaculatory duct, 37 via the prostatic utricle, and 20 under the guide of TRUS, the operation time ranging from 25 to 75 minutes. Sperm was detected from the seminal vesicle fluid in (92.06%) of the azoospermia patients (58/63) during the surgery and in 77.78% of them (49/63) in semen analysis at 1 week postoperatively. Fifteen hematospermia and 12 spermatocystitis patients were cured. Postoperative follow-up found 20 cases of water-like semen and 3 cases of orchiepididymitis, but no such complications as retrograde ejaculation, incontinence, or rectourethral fistula.@*CONCLUSIONS@#Transejaculatory duct and transprostatic utricle pathways are two common approaches to SVS, while TRUS-SVS may achieve a higher success rate and avoid injury of both the prostate and the rectum.

Laparoscopic radical cystectomy with orthotopic ileal neobladder in the treatment of invasive bladder cancer / 中华肿瘤杂志

<p><b>OBJECTIVE</b>To study the technique and outcomes of laparoscopic radical cystectomy (LRC) and evaluate the efficacy of the urinary reservoir constructed with ileum in patients with invasive bladder cancer.</p><p><b>METHODS</b>From 2005 - 2010, A total of 11 patients with bladder cancer were enrolled in this study. Laparoscopy was performed with 5 trocars. Urodynamic examination was performed, the function of upper urinary tract was tested, and complications were evaluated in all the eleven cases.</p><p><b>RESULTS</b>The mean operation time was 420 minutes (ranged 350 to 490 min) and mean blood loss was 410 ml (ranged 300 to 700 ml). Ten of the 11 patients had complete continence, and one case had incontinence. The average flow rate was 11.5 ml/s. The first pressure of the reservoir was 29 cm H2O, and the maximum pressure was 36 cm H2O. The average capacity was 162 ml and 410 ml, respectively. The outlet pressure was 49 cm H2O. The volume of residual urine was 0 - 35 ml. No evidence of ureteral reflux was noted.</p><p><b>CONCLUSIONS</b>Laparoscopic radical cystectomy is a promising method for the treatment of bladder cancer. Orthotopic ileal neobladder is considered as an ideal form of urinary diversion characterized with low pressure, larger capacity and continence.</p>

Study on adsorption of danshen water-soluble compounds with macroporous resin D301 / 中国中药杂志

<p><b>OBJECTIVE</b>To study the adsorption and enrichment of effective compounds of danshensu, and protocatechualdehyde from Danshen water extracts by macroporous resin D301.</p><p><b>METHOD</b>The change of active compounds was observed by detecting the amount of danshensu and protocatechualdehyde with HPLC.</p><p><b>RESULT AND CONCLUSION</b>Macroporous resins D301 can be used in the process of adsorbing and purifying active compounds of danshensu and protocatechualdehyde, and increase the amount of active compounds in water extracts.</p>
