RESUMO
Objective To investigate the change of intracellular calcium ion concentration in prostate smooth muscle cells of SD rats with chronic abacterial prostatitis under high potassium solution.Methods SD rats were divided into experiment group and control group.The CP model was set up by castration and estradiol injection.The PSMC was cultured and purified in vitro.Laser confocal scanning microscope was used after the ceils were incubated with Quest Fluo-8TM.The cells were treated with high potassium solution,and the change of fluorescence intensity was observed.Results The pathologic specimens of the experiment group showed typical pathologic characteristics of chronic prostatitis under light microscope,the control group without inflammation performance.Using immunocytochemistry method confirmed that the experiment group and the control group were prostate smooth muscle cells.The change of fluorescence intensity of [Ca2+] i in the experiment group and control group in the high potassium solution was 27.86 ± 9.88 and 7.61 ± 4.31.There were statistically significant differences between the two groups (P ＜ 0.01).Conclusions High potassium solution cause intracellular calcium ion concentration increased.
RESUMO
Objective To analyze the diagnosis and treatment for complications of renal caliceal diverticulum with calculi or infection. Methods A retrospective investigation was performed on 29 cases with renal caliceal diverticulum. The 29 cases included 11 males and 18 females aged 18 to 61 years. Among the study group, 3 cases were simple renal caliceal diverticulum, 12 cases were diagnosed as diverticular calculi and 14 cases presented recurrent urinary tract infections including 3 cases with urinary fistula after unroofing and decompression as renal simple cyst from another hospital. Ten cases underwent an open operation that unroofed and decompressed the cyst, and sutured the diverticular neck. Eight cases underwent laparoscopic operation similar to the open operation, including lithotomy in caliceal diverticulum in 2 cases. Eleven cases diagnosed with caliceal diverticular calculi were taken one-stage percutaneous nephrolithotomy including dilating the diverticular neck, remaining the nephrostomy catheter and Double-J ureteral stents, and 1 case was transferred to open operation.Results The open and laparoscopic operations were performed successfully. One case was cured by Double-J ureteral stenting after postoperative urinary leakage. One case was transferred to open operation for the failure of percutaneous puncturation. X-ray examination revealed that there were no remaining stones after the operation. All the patients were followed up for 6 to 24 months without calculi and infection recurrence. Conclusions Stones and infection are common that complications of renal caliceal diverticulum. Percutaneous nephrolithotomy, laparoscopy and other operations were effective and feasible treatment options for cases with complications of renal caliceal diverticulum. Exact diagnosis was very important for treatment of renal caliceal diverticulum before operation.
RESUMO
<p><b>OBJECTIVE</b>To investigate the prevalence of sexual dysfunction in chronic prostatitis patients and its relation with patients' age and the course of disease.</p><p><b>METHODS</b>Questionnaire surveys were completed by 2 000 subjects who met the criteria for chronic prostatitis after clinical examination and expressed prostatic secretion analysis. Included in the questionnaire were: (1) age, height, weight, occupation, course of disease and treatment received; (2) NIH-CPSI; and (3) IIEF-5.</p><p><b>RESULTS</b>The prevalence of sexual dysfunction in patients with chronic prostatitis was 49.0% : 26.2% of the subjects with premature ejaculation, 15.0% with erectile dysfunction and 7.7% with both premature ejaculation and erectile dysfunction.</p><p><b>CONCLUSION</b>The prevalence of sexual dysfunction in patients with chronic prostatitis is high, which is negatively correlated with both the age of the patients (P < 0.001) and the course of the disease (P < 0.001).</p>

Objective To evaluate the endourethral surgery for urethrostenosis and urethratresia. Methods 364 patients with an average age of 43 suffered from urethrostenosis or urethratresia 1 month to 23 years were treated by endourethral surgery,such as internal urethrotomy,transurethral scar resection.The average length of the stricture or atresia was 2.2 cm.Some experiences were summed up. Results Of the 364 cases,the outcome was satisfactory in 343 ( 94.23%).Endourethral surgery was carried out twice for 34 patients and thrice for 18 with successful outcome, 20 patients required open surgery because of urethral angulation caused by pelvic fracture.268 patients have been followed up for 4～138 months,satisfactory voiding has been achieved. Conclusions Endourethral surgery is a safe and efficient treatment for urethrostenosis and urethratresia.It should be considered the treatment of first choice for major urethrostenosis and urethratresia.
