OBJECTIVETo summarize and analyze the clinical features of bladder tumor patients who received transurethral partial cystectomy by 2 microm continuous wave laser, in 1 year post operation follow-up visits.

METHODSFrom December 2007 to May 2008, 47 bladder carcinoma patients were treated with 2 microm laser transurethrally under sacral block. Operation characteristics, operation time, intraoperative hemorrhages and postoperative complications, and pathology staging of the tumor were observed and postoperative follow-up visits were performed.

RESULTSAll of the operation procedures were successful. The surgery time was 5 to 15 minutes. Blood loss in the operation was minimal. There was no obturator nerve reflection, and no hemorrhaging was detected after the operation. The pathological stages can be judged correctly with the obtained specimens. There was one case with peritoneum perforation. The patients received 12 to 17 months of postoperative follow-up visits, and there was no recurrence at the resection site. The survival rate was 100%.

CONCLUSIONSTransurethral partial cystectomy in the treatment of bladder tumor by 2 microm continuous wave laser is a safe, efficient and effective method. The tumor and all the basal part of bladder wall could be excised completely and the pathological stages can be judged correctly using these specimens to fulfill partial cystectomy for the treatment of bladder carcinoma.

OBJECTIVESTo observe the vaporesection efficiency of the 2 micron laser to the prostatic gland in benign prostatic hyperplasia, and investigate the method of estimating the amount of the vaporesected prostatic tissues during transurethral vaporesection of the prostate using the 2 micron laser system in the treatment of benign prostatic hyperplasia.

METHODSTotal 9 fresh prostatic gland specimens were obtained from patients with BPH under open surgical procedures, and vaporesected under a simulated transurethral environment with the 2 micron laser system immediately after weighted. Energies and time consumptions were noted, collections of vaporesected tissue specimens and the remnants of the prostatic glands were weighted after the procedures. The ratios of the vaporized tissues and the collected tissues to the whole vaporesected tissues were calculated respectively. The vaporesection efficiency of the 2 micron laser to the prostatic tissues was also calculated.

RESULTSAmong the total lost tissues, about (65.6 +/- 1.5) percent of which were that of vaporized, and nearly (34.5 +/- 1.5) percent were resected. Linear correlation between the weight of collected prostatic tissue(x) and the weight of prostatic gland specimens(y) could be defined as a formula of [y = 3.245x - 6.475 (t = 15.097, P = 0.000)].

CONCLUSIONThe amounts of the whole prostatic tissues removed by the 2 micron laser could be calculated from the collected resected prostatic specimens under a simulated transurethral surgical procedure.

OBJECTIVETo summarize the 5-year follow-up to 2 micron continuous wave laser vaporesection for the treatment of patients with low urinary tract symptoms (LUTS) secondary to benign prostatic hyperplasia (BPH), and evaluate the safety and clinical effects of the treatment.

METHODSFrom October 2006 to September 2007, 236 cases with low urinary tract symptom secondary to BPH were treated transurethrally under epidural or general anesthesia using the 70 Watt 2 micron laser system. Vaporesection of the prostate was performed with the traditional "U" or the "dividing" method. The 210 cases who met the inclusion criteria in this study were selected for further observation. Baseline and perioperative data were recorded and evaluated in resection time, transfusion rate, catheter-time, improvements in maximal urinary flow rate (Qmax), international prostate symptom scores (IPSS), quality of life (QoL), and post voiding residual volume (PVR).

RESULTSOut of the 210 cases, 179 cases were followed up to 5 years finally. All the surgical procedures were successfully conducted under epidural or general anesthesia. Mean operation time was (80 ± 22) minutes, and mean retrieved prostatic tissue was (24.9 ± 4.2) g. Resected prostatic tissues could be easily flashed out of the bladder. There were no significant differences in serum sodium concentrations and hemoglobin levels before and after the surgery. Mean catheter time and hospital stay was (114 ± 35) hours and (5.7 ± 1.9) days respectively. Only one postoperative secondary hemorrhage was found and treated with blood transfusion. During the 5-year follow-up, Qmax increased from (8.6 ± 3.5) ml/s preoperatively to (23.6 ± 4.2) ml/s by the end of the follow-up (P < 0.01), IPSS and QoL-Score improved from 25.3 ± 5.2 and 4.1 ± 1.3 to 6.1 ± 3.0 and 1.4 ± 0.8 respectively (P < 0.01), and PVR decreased from (248 ± 89) ml to (15 ± 13) ml. The 3 patients developed urinary incontinence and recovered 3 months later through functional exercises with the help of acupuncture. Five patients were found to have urethral stricture 3 months after the surgery and recovered with the treatment of urethral dilatation (3 cases) or internal urethrotomy (2 cases) respectively.

CONCLUSIONSTransurethral vaporesection of prostate using the 2 micron continuous wave laser system is a safe and effective treatment for benign prostatic hyperplasia with obvious improvements in subjective and objective voiding parameters, which were evident at 3 months after the surgery and were sustained throughout the 5-year long-term follow-up.

OBJECTIVETo analyze the influence of benign prostatic hyperplasia (BPH) drugs on incidence and pathology grading of prostate cancer in China.

METHODSRetrospectively investigated the history of drug treatment in 1029 cases of BPH in patients from February 1998 to December 2004. According to the history of drug use, the patients were divided into 4 groups: finasteride group, alpha-receptor inhibitor group, finasteride and alpha-receptor inhibitor combination group and control group (untreated group). We gathered pathology sections of patients in all groups, and gave Gleason Score to each. The difference of incidence and pathology grading of prostate cancer were analyzed by Stata 7.0.

RESULTSThe incidence of prostate cancer in the population of our study was 13.5%; The incidence in finasteride group, alpha-receptor inhibitor group, combination group and control group was 9.8%, 16.0%, 10.3% and 18.6%, respectively. There was significant difference between the two groups with the use of finasteride and the two groups without it (P < 0.05). In our study, the ratio of middle or high level pathology grading (Gleason ≥ 7) in prostate cancer patients was 58.3%, the ratio of middle or high level pathology grading prostate cancer patients in the four groups was 71.4%, 59.6%, 67.7% and 40.0%, respectively. In the comparison of composition ratio of middle or high level prostate cancer, there was significant difference between the two groups with the use of finasteride and the two groups without it (P < 0.05).

CONCLUSIONSFinasteride can lower the risk of prostate cancer, but increase the pathology grade of the prostate cancer which has occurred in the same time. The alpha-receptor inhibitor does not have the same effect.

OBJECTIVETo assess the recovery of the reproductive endocrine function in rats following orthotopic transplantation of fetal ovarian allograft.

METHODSNinety female SD rats (50-60 days old) were randomized into graft recipient group (n=50), positive control group (n=20), and negative control group (n=20) to receive orthotopic transplantation of fetal (17-19 gestational days) ovaries following bilateral oophorectomy, sham abdominal surgery, and bilateral oophorectomy, respectively. At 45 days after the surgeries, serum estradiol and progesterone levels were measured and the ovaries were removed for evaluation of the ovarian volume and follicle development.

RESULTSOn day 45 after the operations, the estradiol or progesterone levels showed no significant difference between the recipient group and positive control group (P>0.05), but both were significantly lowered in the negative control group (P<0.05). The ovarian volume was comparable between the recipient group and positive control group (P>0.05), and optical microscopy showed follicles in different stages of development and formation of corpus luteum in the ovaries in both groups.

CONCLUSIONFetal rat ovary allografts can develop into functional ovaries capable of ovulation to restore the reproductive endocrine function of recipient female rats.

OBJECTIVETo compare the therapeutic effects of the greenlight photoselective vaporization of prostate (PVP) and transurethral electrovaporization resection of prostate (TUVP) for the treatment of symptomatic benign prostatic hyperplasia (BPH).

METHODSOne hundred and sixty-three cases of BPH were treated with PVP and TUVP. All patients were followed up with International Prostatic Symptom Score (IPSS), quality of life (QOL), blood loss, operative time, indwelling catheterization, mean Qmax, residual urinary volume (RUV) and operative complications.

RESULTSIPSS, QOL, Qmax and RUV were significantly improved after either of the procedures (P < 0.05), no significant difference in the improvement of subjective symptoms and objective signs had been noted with the different procedure (P > 0.05). Mean operative time was (37 +/- 15) min for TUVP and (45 +/- 28) min for PVP, the resection time was longer for PVP than TUVP (P > 0.05), but the intraoperative bleeding and catheterization time were less for PVP than TUVP (P < 0.05). Postoperative complications were less for PVP than TUVP (P < 0.05). The incidence of hematuria in TUVP group had been 41.4%, and urinary irritation after PVP group was 55.2% (P < 0.05).

CONCLUSIONSPVP has the same therapeutic effect as TUVP and less adverse side effects than TUVP. It is a new technique for the treatment symptomatic BPH.
