Through observation on changes of inflammatory mediators and hemorrheology among chronic prostatitis patients before and after treatment, this study was aimed to compare the therapeutic differences between the applications of standard retention enema ofQu-Yu Tong-Bi (QYTB) decoction andα-blockers combined with quinolones. During the same period, 164 patients of the Henan Province of Traditional Chinese Medicine Hospital were randomly divided into the observation group and control group, with 62 cases in each group. Retention enema of QYTB decoction was given in the observation group; andα-blockers combined with quinolones were used in the control group. The treatment course was one month. And the differences were compared. The results showed that the total effective rate of the observation group was 79.03% (49 cases); and that of the control group was 61.29%(39 cases). There was statistical significance between two groups (P < 0.05). There was statistical significance on TNF-α, IFN-γ and NIH-CPSI score comparison before and after treatment of two groups (P < 0.05). Compared to the control group, the posttreatment TNF-α, IFN-γ and NIH-CPSI score in the observation group had significant difference (P < 0.01). There were no significant differences on the whole blood viscosity (high shear), plasma viscosity and erythrocyte deposited test value contrast between pretreatment and posttreatment in the control group. There were significant differences on the whole blood viscosity (high shear) and plasma viscosity between pretreatment and posttreatment in the observation group (P < 0.05). However, there was no significant differences on erythrocyte deposited test value contrast. It was concluded that both methods had certain therapeutic effect in the treatment of chronic prostatitis. However, the effect of retention enema of QYTB decoction was better than the treatment of quinolones combined withα-blockers.

Objective To describe the single needle running suture method for the urethrovesi-cal anastomosis during laparoscopic radical prostatectomy(LRP). Methods Forty-five patients of prostate cancer underwent LRP with the single needle running suture method. The technique was initi-ated by performing a fixing suture at the posterior lip of bladder neck at 4 o' clock and tying the first knot. Another suture at the nearby position of the first suture was performed to leave the first knot outside. From 5 o' clock to 8 o' clock, sutures were performed every one o' clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were per-formed every 3 sutures. After completing the full circumference, the needle was drawn at the 2 o' clock for the second knot. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. Any remaining leakage could be closed with additional interrupted su-tures. Results All urethrovesical anastomosis were completed successfully. The mean anastomosis time was 16 rain(from 12 to 25 min), and mean operative time was 132 rain (112 to 185 rain). The mean catheterization time was 9 d(7 to 14 d). Three temporal urinary leaks requiring prolonged cathe-terization were identified. Forty-four patients had total urinary control in 1 year postoperatively and no other short-term or persistent complication was found with a mean follow-up of 21 months. Conclu- sion The single needle running suture method could be a simple and safe method for urethrovesical anastomosis during LRP.

The expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder (TCCB) and its clinical significance were investigated. Immunohistochemistry was used to detect KAI1/CD82 and MRP-1/CD9 protein expression in 52 TCCB specimens. Correlation between the expression of KAI1/CD82 and MRP-1/CD9 to clinicopathologic factors was statistically analyzed. The results showed that the positive rate of KAI1/CD82 and MRP-1/CD9 in TCCB was 50% and 61.5%, respectively. The MRP-1/CD9 and KAI1/CD82 expression was significantly associated with grade of TCCB (P<0.05), but no correlation was found between MRP-1/CD9 or KAI1/CD82 expression and clinical stage of TCCB (P>0.05). The expression level of MRP-1/CD9 and KAI1/CD82 in recurrent TCCB samples was lower than that in non-recurrent samples (P<0.05). Meanwhile, the correlation between the KAI1/CD82 expression and MRP-1/CD9 expression was statistically significant (r=0.316, P<0.05). It was concluded that KAI1/CD82 and MRP-1/CD9 expression may be important prognostic indicators and potentially useful for assessing the biological behavior of TCCB.

The single needle method for urethrovesical anastomosis with strengthened posterior fixation during laparoscopic radical prostatectomy was explored. The method was initiated by performing a fixing suture with a knot at 4 o'clock of the posterior lip of bladder neck, and another suture at nearby position was performed to leave the knot outside. From 5 o'clock to 8 o'clock, sutures were performed every one o'clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were performed every 3 sutures. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. After completing the full circumference, the needle was drawn near the 4 o'clock and tied at the tail end. Any leakage could be closed with additional interrupted sutures. The clinical data of 89 patients who underwent this method were retrospectively compared with those of 23 patients who underwent the single knot method. The results showed that the anastomosis, operative and catheterization time was 17.6+/-4.7 min, 134.0+/-10.7 min and 6.5+1.6 days respectively. There were 3 temporal urinary leakages identified in 89 cases requiring prolonged catheterization. No urinary leak and anastomotic stricture was confirmed, and 95.2% patients had total urinary control. It was concluded that this method was simple and safe for urethrovesical anastomosis.

Objective To evaluate the efficacy and feasibility of laparoscopie intervention for congenital obstructive megaureter in children. Methods Eleven children with congenital obstructive megaureter(left in 4,right in 7)underwent laparoseopie ureteroplasty.One had congenital ureter oririce stenosis,9 had been diagnosed as simple congenital ureter orifice stricture,1 had recurrent ureter orifice stricture after open ureterovesical reimplantation.B-ultrasound and IVU showed severe hydronephrosis in 7 cases and moderate in 4. Results The operation was successful in all cases and none had urine leakage.The mean operating time was 103.0±35.3 min(range 70-190 min).The mean blood loss was 18.0±9.5 ml(range 10-40 ml)and the mean postoperative hospital stay was 8.0±1.4 d(range 7-10 days).The double J stent was removed 6 weeks after operation.The patients were followed up for 3-24 months(mean,6 months).Cystography showed no reflux in all cases during follow-up. Conclusion Laparoscopical ureteroplasty could be a minimal invasive,less suffering technique for the treatment of congenital obstructive megaureter in children.

Objective To develop and evaluate a porcine model for training the single needle running suture method of laparoscopie urethrovesical anastomosis(LUA). Methods Twenty minipigs with mean weight of 30kg were general anaesthetized with Sumianxin solution 0. 1 ml/kg intramuscularly. Pneumoperitoneum was created by insufflation of carbon dioxide by a veress needle inserted through the umbilicus. One 10mm port and two 5mm ports were positioned after the establishment of pneumoperitoneum. The intestine was used as "bladder". The procedures were completed with the single needle running suture method of laparoscopic urethrovesical anastomosis. Six trainees performed the LUA procedure based on the models during a laparoscopic training course, following the technique used in the operation room. The learning curve was analyzed by operative time. Results The porcine model for laparoscopic training was established successfully and 3 LUAs could be performed on each pig. Each trainee performed 10 LUAs based on the models during the training course of laparoscopic urology. The operative time declined from (55.3±10. 4)min initially to (22.4±4.8)min (P＜0. 01) after the training course. At the end of training, all trainees could accomplish a watertight LUR procedure on the model. Conclusions The establishment of the training model is feasible. The trainees could acquire the skills necessary to perform LUA in vivo based on this model. The model provides a platform for training the basic techniques of LUA procedures.

ObjectiveTo investigate the clinical value of Longbeisan application at Shenque （CV 8） combined with oral administration of Chinese medicine in the treatment of premature ejaculation （PE）. MethodA total of 98 PE patients treated in the andrology department of the First Affiliated Hospital of Henan University of Chinese Medicine at the same time period were randomly assigned into an observation group and a control group， with 49 patients in each group. The observation group received Longbeisan application at Shenque （CV 8） combined with oral treatment of Chinese medicine according to syndrome differentiation， and the control group was treated with dapoxetine hydrochloride tablets. The treatment in both groups lasted for 8 weeks. The intravaginal ejaculatory latency time （IELT）， Chinese index of premature ejaculation-5 （CIPE-5） score， patient's sexual life satisfaction， spouse's sexual life satisfaction， effective rate， and adverse reaction incidence were compared between the two groups. ResultAfter treatment， the observation group had higher total effective rate than the control group ［（85.71% （42/49） vs. 67.35% （33/49）， χ²=6.262， P<0.05］. The IELT， CIPE-5 score， and patient's and spouse's satisfaction scores after treatment increased compared with those before treatment （P<0.01）， and the increases were more significant in the observation group （P<0.05， P<0.01）. The clinical effect of the observation group was better than that of the control group. During the treatment， 7 （7/49，14.29%） patients in the control group and 2 ，2/49，4.08%） patients in the observation group showed adverse reactions， which indicated the safety of the observation group was better than that of the control group （χ²=9.000， P<0.05）. In the follow-up period， 11 （11/49，22.45%） patients in the control group and 3 （3/49，6.12%） patients in the observation group showed aggravation of symptoms， which meant that the observation group had better lasting effect （χ²=0.317， P<0.05）. ConclusionLongbeisan application at Shenque （CV 8） combined with oral administration of Chinese medicine has better clinical effect， stronger safety， and longer effect than dapoxetine hydrochloride in the treatment of PE.

Objective To study the endoscopic anatomical structures in retroperitoneal space and to share experiences of retroperitoneoscopic radical nephrectomy. Methods Between January 2006 and March 2008, a total of 85 patients underwent retroperitoneoscopic radical nephrectomy. Thirty-eight tumors were on the left kidney and 47 on the right side. The mean tumor size was 5.5± 1.7 cm in diameter (2.5 to 10.5 cm). There were 74 cases in clinical stage T1N0M0 and 11 cases in T2N0M0. Following the principle of radical nephrectomy outside the renal fascia, the whole surgical procedure was performed along "2 spaces" and "2 poles". The ventral attachment of the kidney was dissected in anterior pararenal space between peritoneum and anterior renal fascia. The dorsal attachment was dissected in anterior psoas space between posterior renal fascia and psoas fascia. The cepha-lic attachment was dissected up to the subdiaphragmatic and down to iliac fosse. During the proce-dure, important anatomic structures such as parietal peritoneum and its reflexion, anterior renal fasci-a, lateroeonal fascia, posterior renal fascia, psoas muscles, greatvessels and their branches were care-fully identified. Results One case was converted to open surgery because of severe and extensive ad-hesion of the right kidney to the adjacent tissues. The other 84 procedures were successfully comple-ted. The median operative time was 65 rain (range 50 to 165 min) and median estimated blood loss was 58 ml (range 25 to 600 ml). Of all operations, peritoneum perforation occurred in 5 cases and small vessel injuries around renal pedicles were observed in 6 cases. Major complication such as great vessel injury was not observed. Mean follow-up of all 85 patients was 10 months (range 2 to 25 months). No local recurrence and port site tumor seeding was found. Conclusion During retrope-ritoneoscopic radical nephrectomy, studying anatomical features of renal area and recognizing impor-tant anatomic structures will help to improve the safety of the surgery and reduce morbidities.

Objective To develop a staged laparoscopic training program for performing the ana-tomic retroperitoneoscopic adrenalectomy(ARA), and to determine its safety and feasibility. Me-thods Five young urological doctors without previous experience in open adrenalectomy were selected third period, trainees acted as camera holder first, then performed simple operations such as laparo-scopic renal cyst unroofing. Finally, they performed 30 ARA independently under the mentor's super-vision. Pheochromocytoma was ruled out for its large tumor size and potential cardiovascular risk. The patient selection criteria were the same as those of the initial 30 cases performed by the tutor. Preope-rative data of the initial 30 ARA performed by each trainee and tutor which included gender, age, body mass index, tumor size, tumor location and pathological diagnosis of tumor were compared between trainees and the tutor. The intraoperative and postoperative data of 150 ARA in the trainees were compared with the initial 30 ARA of the tutor. These included mean operative time, estimated blood loss, length of hospital stay, conversion rate, complication rate. Qualitative and quantitative data were compared between the groups using x2 and t test statistics methods by SPSS 12.0 for Windows, except operative time, which was from a nonnormal distribution. A P value less than 0.05 was consi-dered to be statistically significant. Results Preoperative data of the initial 30 ARA performed by each trainee were marched to those of the mentor (all P>0.05). All ARA were completed successful-ly. No procedure converted to open surgery. The median operative time of the trainees was 82 min (range 59-133 min), which was less than that of the tutor [132 min (range 73-230 min), P< 0.01]. And the trainees' learning curve was flatter than their tutor's. Estimated blood loss and length of hospital stay for the 5 trainees and the tutor were 62.2±22.0 ml, 4.8±1.3 d and 63.9±21.1 ml, 4.5±1.4 d respectively. There was no significant difference between these results (both P>0.05). No major complication was observed. Though the total perioperative complication rates were no diffe-rence between the trainees and their tutor (8.0% versus 13.3%, P>0.05), intraoperative minor complication rates of the trainees (1.3%) was less than that of the tutor (10.0%, P<0.05). Con-clusion The staged laparoscopic training is safe and feasible for young urological doctor to study in performing ARA.
