ABSTRACT
ObjectiveTo investigate the efficacy of rapamycin combined with CsA/Tacrolimus (Tac) in chronic allograft nephropathy (CAN).MethodsFifty-three cases of CAN accepted the quadruple immunosuppressive drug program,which contained rapamycin combined with CsA/Tac and MMF and prednisone,and CsA/Tac and MMF were reduced to the original amount of 25％ to 50％.After treatment for 12 months,more relevant indicators,including serum creatinine,glomerular filtration rate,serum cholesterol,triglycerides,urinary protein,GPT and bilirubin and other changes were observed.ResultsIn the patients receiving quadruple regimen of rapamycin during 12 months,the blood Ccr was decreased from (161.51 ± 106.48)μmol/L before treatment to (126.51 ± 56.2)μmol/L after treatment for 6 months (P＜0.05) and to (123.43 ± 54.18)μmol/L after for 12 months (P＜0.01).The GFR was increased from (0.754 ± 0.302) ml/s before treatment to (0.952 ± 0.347)ml/s after treatment for 6 months (P＜0.05) and to (1.007 ± 0.394) ml/s after treatment for 12 months (P＜0.01).Cholesterol and triglycerides in patients had no significant change before and after treatment.The positive rate of proteinuria after treatment showed an increasing trend from 9.4％ before treatment to 26.4％ after treatment for 12 months.ConclusionThe quadruple program of rapamycin combined with CsA/FK506 and MMF can significantly improve Ccr and GFR in patients with CAN,but it can increase the incidence of proteinuria in patients:
ABSTRACT
Objective To analyze the surgical technique of extraperitoneal laparoseopic radical prostatectomy with neurovascular bundle preservation and its effect on micturition control and sexual function in patients with prostate cancer. Methods Twenty-two patients with a median age of 66. 9 years underwent extraperitoneal laparoscopic radical prostatectomy with neurovascular bundle preservation from October 2005 to March 2009 in our hospital and Shanghai Changzheng hospital. All patients had no erectile dysfunction. According to the pathology, there were 2 cases of PIN high grade, 4 cases of Tla-b, 9 cases of Tlc, 4 cases of T2a-b, 2 cases of T2e and 1 case of T3a. Results All operation were successful and no case was conversed to open surgery. The average operation time was 225 min and the mean blood loss was 850ml. The amount of blood loss in 1 case was 1200 ml because of injuring deep dorsal vein of penis. 4 cases received blood transfusion, gatheters of all patients were removed 2 weeks after operation, and three cases with mild incontinence regained continence of urine after 6 months follow-up. No patient occurred postoperative vesicourethral anastomotic leakage of urine. The surgical margin of 1 case was positive. No biochemical index of prostatl cancer recurred during postoperative follow-up of 10-24 months (with an average of 16 months). 20 cases had sexual function recovery after operation. Conclusions The extraperitoneal laparoscopie radical prostatectomy with neurovascular bundle preservation for prostate cancer is a safe and effective treatment method with less bleeding, small damage and less complications. It can guarantee the maximum of micturition control and sexual function, which is worthy to be popularized in the clinic.
ABSTRACT
Objective To summarize the clinical experie nce in the diagnosis and treatment of cystolithiasis complicated by squamous cel l carcinoma (SCC) of the bladder. Methods Retrospective analysis was performed in 28 patients (19 men and 9 women) with cystolithiasis c omplicated by SCC of the bladder.Their age ranged from 26 to 68 years with a mea n of 33 years.The disease course of cystolithiasis ranged from 2 to 18 years wit h a mean of 4.5 years. Among the 24 cases who underwent urine cytology,atypical cells were found in 19 cases.KUB showed solitary stone of the bladder in 5 case and multiple stones in 23.Space-occupying lesions were noted in 11 cases on IVU ,in 17 cases on B-ultrasonography and CT scan.Cystoscopy was performed in 28 ca ses, and tumors were found in 21 cases.The size of the tumors ranged from 1.2 cm ?1.5 cm to 2.2 cm?5.0 cm. Partial cystectomy was performed in 21 cases, includ ing ureterocysto-transplantation in 6 cases.Radical cystectomy was performed in 7 cases. Results Pathology revealed SCC of the bladder in all 28 cases,including G_1 in 11 cases,G_2 in 12 cases,G_3 in 5 cases;T_1 in 11 cases,T_2 in 12 cases,T_3 in 5 cases. Twenty-two patients were followe d up for 1 to 8 years with a mean of 3 years. The 1- and 5-year survival rates were 63.6% (14/22) and 16.7% (3/18),respectively. Conclusions Cystolithiasis is the main cause of SCC of the bladder. Early diagnosis a nd surgical treatment is very important for such patients.
