ABSTRACT
Objective: To investigate the role of prostate specific antigen(PSA) in screening for prostate cancer. Methods: The serum PSA of 4 848 males over 50-years old for serum PSA was evaluated,respectively out of them 33 cases diagnosed as prostate cancer(screening group) were compared in terms of age distribution,level of PSA,clinical stages,Gleason score and treatment modalities with 28 patients in our hospital(clinical group). Results: In the screening group,the positive percentage account for 9.5%(PSA≥4 ng/ml) and the PCa positive rate was 6.8‰(33/4 848).The average age of the patients(73.2?8.0) was insignificant different between these two groups.The percentage of the cases beyond 20 ng/ml PSA in the screening group was significantly lower than that in clinical group,with 42.4% and 71.5% respectively.Furthermore,the cases with clinical stage A+B accounted for 69.7% in the screening group,while it was 35.7% in the clinical group(P
ABSTRACT
Vasoseminal vesiculography is becoming more and more valuable to the diagnosis of seminal ductal system diseases. Vasography can be performed by either trans-scrotal injection into the vas deferens, or transperineal injection into seminal vesicle, or retrograde insertion of a catheter into the opening of the ejaculatory duct. A good knowledge of the indications and proper judgement of the X-ray signs may significantly improve the diagnosis and treatment of the diseases of the seminal vesicle and ductal system.

<p><b>OBJECTIVE</b>To study the diagnosis and treatment of prostate cancer after prostatectomy for benign prostatic hyperplasia (BPH).</p><p><b>METHODS</b>Twelve cases of prostate cancer after prostatectomy for benign prostatic hyperplasia were reviewed and studied. The mean intervals between prostatectomy for BPH and the diagnosis of prostate cancer was 10 months to 14 years, 5.6 years on average. The main symptoms were dysuria, hematuria and pain. Serum prostate specific antigen (PSA) was elevated in 11 cases. Digital rectal examination (DRE) was abnormal in 8 cases. Three cases were in clinical stage B, 3 in stage C and 6 in stage D. Ten cases received combined androgen blockade therapy. Monotherapy with surgical castration was given to 2 cases. Three patients with urinary tract obstruction received additional treatment of TURP.</p><p><b>RESULTS</b>During the 4 months to 8 years follow-up, 3 patients died, 6 remained stable and 2 deteriorated.</p><p><b>CONCLUSION</b>Surgery for BPH could not prevent the development of prostate cancer. PSA and DRE were the main methods for the diagnosis of this prostate cancer.</p>

Objective: To evaluate the efficacy and safety of Naftopidil on patients with female urethral syndrome (FUS). Methods: Self-controlled clinical trial was performed in patients with FUS. Thirty-eight patients were treated with naftopidil tablet 25mg/po/qn for 4 weeks after one-week washout period. The effects were evaluated mainly by female urethral syndrome score (FUSS) and quality of life (QOL). Results: FUSS began to decrease after 2 (week's) administration and decreased significantly after 4 weeks' treatment. It had statistically significant difference of FUSS and QOL after treatment compared with control (P
ABSTRACT
Objective:To make an ideal model for liver transplantation. Methods:On the basis of cuff technique,we carried out 62 cases of orthotopic liver transplantation in 3 months. In the transplantation,we anastomosed the portal vein and subhepatic vena cava with cuff and conneted the suprahepatic vena cava to the recipient's diaphragm with 9-0 running suture. Results:The average time of acquiring donor liver was 32 minutes, reqairing liver was 12 minutes,unhepatic phase was 18 minutes.62 liver transplantation operations were carried out ,in which the operation success rate in late 30 cases was 90%. Conclusion:The results show that the model is stable and can be used in the experiment of liver transplantation.
ABSTRACT
Objective:To investigate the incidence of anemia in early and middle pregnancy and to provide better medical service to pregnant women.Methods:We included in this study 556 women in early or middle pregnancy received in our hospital in 2007,detected the levels of hemoglobin and analyzed the incidence of anemia in different periods of pregnancy according to the WHO and Chinese national standard.Results:The anemia incidence was 15.83% according to the WHO standard and 1.81% according to the Chinese national standard,significantly higher in the middle period than in the early trimester of pregnancy(P
ABSTRACT
Objective To explore the effectiveness of tension-free vaginal tape (TVT) for female stress urinary incontinence. Methods Thirteen cases of stress urinary incontinence confirmed by urodynamics examinations underwent treatment with tension-free vaginal tape through the anterior vaginal wall under an epidural anesthesia. The patients were positioned in the lithotomy position. Dissection was performed alongside the urethra bilaterally by way of the anterior vaginal wall. A TVT suprapubic tape was passed through the lower abdominal wall and was positioned and adjusted. Results The operation time was 15~45 min (mean, 35 min). Follow-up observations for 6~24 months (mean, 13 months) in 13 cases revealed 12 cases of cure and 1 case of improvement. No recurrent urinary incontinence or dysuria was noted. Conclusions Treatment with TVT is a simple, effective and minimally invasive procedure for stress urinary incontinence, with a short operative time and a quick postoperative recovery.
ABSTRACT
Objective To investigate the effects of combination of retinoids and interferon ?-2a on growth inhibition and apoptosis induction in bladder cancer cell lines. Methods Four bladder cancer cell lines and two retinoids,all-trans-retinoic acid (ATRA),9-cis retinoic acid (9cRA),combined with interferon ?-2a(IFN),were used in the study.The abilities of these agents to inhibit growth,induce apoptosis were compared and the expression of nuclear retinoid receptors,Stat1 protein were measured by means of TUNEL,FCM,RT-PCR and Western blot. Results Most of the bladder cancer cell lines were resistant to the effect of ATRA and 9cRA on growth inhibition and apoptosis induction.The effects of ATRA and 9cRA on cell growth and apoptosis were enhanced by IFN ?-2a.Combination of ATRA and IFN ?-2a induced RAR? and Stat 1 expression in three bladder cancer cell lines. Conclusions INF ?-2a synergizes with the inhibitory effect of ATRA and 9cRA on the growth inhibition and apoptosis of bladder cancer cells in vitro,up-regutation of Stat1 gene expression could be the main molecular mechanism.
ABSTRACT
Objective To study the diagnosis accuracy and the treatment sequelae of adenocarcinoma of urinary bladder. Methods 41 cases of urinary bladder adenocarcinoma have been encountered from 1980 to 2000,all of them had undergone operation and the diagnosis being assessed on histopathology studies.There are 18 cases of primary bladder adenocarcinoma,among which 8 had undergone radical cystectomy and 10 partial cystectomy.Among 12 cases of urachal adenocarcinoma extending to the bladder,11 received extended resection.All the 11 patitents with metastatic focus in the bladder underwent local ablation. Results Urinary bladder adenocarcinoma comprised 3.2% of the bladder cancer.Thirty seven patients have been followed up for five months to ten years.The 1 year survival rate was 51.3%(19 cases),the 2 year survival rate 43.2%(16 cases) and the 5 year survival rate 21.6%(8 cases). Conclusions Radical total cystectomy is the treatment of choice for primary adenocarcinoma of bladder and extended partial cystectomy seems to be the best for urachal adenocarcinoma. Comprehension therapy should be undertaken for patients with metastatic adenocarcinoma or tumor recurrence so as to improve the survival rate.
ABSTRACT

ABSTRACT
Objective To highlight the diagnostic and t herapeutic procedures for extra-adrenal pheochromocytoma. Methods Thirty-eight cases of extra-adrenal pheochromocytoma proven patholo gically from 1998 to 2002 were reviewed and studied.Hypertension was observed in 34 cases and intermittent macrohematuria in 4 patients.Another 2 cases were adm itted to hospital with abdomen masses through routinely physical examination.Uri nary VMA,serum and urinary catecholamine were measured in 33 cases.38 cases had B-model ultrasound examination and 34 cases took CT scan.The level of urine VMA elevated in 30 cases(91%) and serum or urinary catecholamine were elevated in 2 8 (85%).The positive rates of localization of B-ultrasound and CT were 92% and 100%,respectively.29 cases took ?-receptor blocker for at least 2 weeks preope ratively.There were 6 cases operated under epidural anesthesia and 32 general an esthesia.Six cases were operated transvesical.10 cases with lumber incision and 19 with abdominal incision.The other 3 cases operated laparoscopically. Results Tumor location,6 cases in bladder wall,7 in renal hilum, 9 in upper pole of kidney,4 in low pole,10 in anterio-lateral to the adrenal gl and,and 2 cases of multifoci.The specimens were from 2 to 9 cm in size.Among 34 cases with hypertension,the blood pressure of 26 patients return to normal and 2 cases were still hypertensive.10 cases were assayed as malignant pheochromocyto ma.There were 9 cases of recurrence or metastases and 5 patients died during fol lowed-up from 13 months to 10 years. Conclusions Urine VMA level is a useful marker to detect extra-adrenal pheochromocytoma and CT sc an is the most reliable in localizing the lesions. 131I-MIBG scintigra phy is of great value for the localization and quantitative for extra-renal phe ochromocytoma with high sensitivity and accuracy.It may be also used as a therap eutic method.Surgical manipulation of the tumor is the best management and metic ulous perioperative management is extremely important.Measuring the level of uri nary catecholamine can monitor the recurrence or metastasis of the tumor.
ABSTRACT
Objective To evaluate the modified Stamey bladder neck suspension for female stress urinary incontinence. Methods 52 cases with an average age of 46 and an average stress incontinence history of 7.5 years underwent the modified Stamey procedure,18 cases being degree Ⅰ,21 degree Ⅱ and the other 13 degree Ⅲ. Results 32 cases were treated before 1994 and the outcome was evaluate at 3.6 years and 9.6 years postoperatively.There were 3 failures because of operative complication.The cure rates and failure rates at 3.6 and 9.6 years were 87.5%,68.8% and 6.2%, 21.9%,respectively.20 cases were treated after 1994 with a follow up of 4.3 years.The cure rate has been 90.0%. Conclusions The Stamey procedure yields high initial cure rates yet the latter declines with time.
