[Erectile function evaluation after adult circumcision].

OBJECTIVE: To evaluate the erectile function of adults after circumcision. METHODS: Ninty-five patients were investigated on erectile function by questionnaire before and after circumcision, respectively. RESULTS: Eighteen patients suffered from mild erectile dysfunction before circumcision, and 28 suffered from mild or moderate erectile dysfunction after circumcision(P = 0.001). Adult circumcision appeared to have resulted in weakened erectile confidence in 33 cases(P = 0.04), difficult insertion in 41 cases(P = 0.03), prolonged intercourse in 31 cases(P = 0.04) and improved satisfaction in 34 cases(P = 0.04). CONCLUSIONS: Adult circumcision has certain effect on erectile function, to which more importance should be attached.

[Malignant fibrous histiocytoma of the prostate: one case report].

OBJECTIVE: To probe into the diagnosis and treatment of malignant fibrous histiocytoma (MFH) of the prostate. METHODS: One case of MFH of the prostate was diagnosed and treated surgically by radical remocal of the lesion, resection of the rectum and sigmoidoctomy. The clinical features, diagnosis and treatment of MFH of the prostate were reviewed and presented. RESULTS: The patient experienced recurrence 3 weeks after operation, and then underwent radiotherapy. Two months after operation the patient died of metastasis. CONCLUSION: MFH of the prostate has been rare clinically, with poor prognosis. Early and aggressive surgical removal of the primary lesion followed by adjuvant therapy is recommended for the treatment of the disease.

[Diagnosis and treatment of tuberculosis in the male genital system].

OBJECTIVE: To probe into and improve the diagnosis and treatment of tuberculosis (TB) in the male genital system. METHODS: Fifteen patients with the male genital system TB established by microbiological and pathological examinations were retrospectively reviewed. RESULTS: The male genital system TB was diagnosed by history, physical examination, semen analysis, TB culture and biopsy. Treatment consisted of antituberculous chemotherapy for all the patients before and/or after operation, including 5 cases of epididymectomy and 6 cases of orchi-epididymectomy. CONCLUSION: The male genital system TB tends to be atypical and semen polymerase chain reaction of TB (TB-PCR) may provide a new specific means for diagnosis in case of clinical suspicion. Surgical approaches should be cautiously adopted, especially for young patients.

[Investigation of infection risk and the value of antibiotic prophylaxis during transrectal biopsy of the prostate by endotoxin determination].

OBJECTIVE: To clarify the value of endotoxin determination in evaluating the infection risk and antibiotic prophylaxis during transrectal biopsy of the prostate. METHODS: Forty-eight patients were divided into four groups randomly. Group A (12 patients) were not treated before biopsy. Group B (13 patients) received antibiotic prophylaxis therapy. Group C (12 patients) underwent clusis. Group D (11 patients) received combined treatment. Urine and blood samples of the patients were obtained before and after prostatic biopsy. All samples were cultured for bacteria and investigated for endotoxin concentration by limulus quantitative azo color test. RESULTS: No significant difference in either serum endotoxin or blood bacterial cultures was noted before and after prostatic biopsy (P < 0.05) in all the groups. A significant increase was observed in urine endotoxin after biopsy compared with that before biopsy in Groups A and B (P < 0.05). There was no significant increase in urine endotoxin after biopsy compared with that before biopsy in Group C and D. The positive incidence of urine bacterial culture was significantly increased (P < 0.05) in patients of Group A and B. CONCLUSION: Circulation infection risk following prostatic biopsy was low. Changes of urinary infection were fewer in patients who had undergone clusis and/or antibiotic prophylaxis than in those who had received no or only antibiotic prophylaxis therapy. Endotoxin determination in urine is a reliable, sensitive and simple method for diagnosis of bacterial infection in patients undergoing transrectal biopsy of the prostate.
