[Treatment of penile strangulation and sexual psychological analysis of the patients].

OBJECTIVE: To find the best treatment of penile strangulation and to analyze the sexual psychological factors of the patients. METHODS: We retrospectively analyzed the experiences in removing foreign objects around the penis in 21 patients aged 19 - 61 years with the strangulation time varying from 10 hours to 4 days. The objects were mostly made of metal or plastics. RESULTS: All the objects were successfully removed, 5 of them with the help of lubricant, 4 by aspirating the corpus cavernosum, 8 by shipping with pliers, 2 with the diamond-tipped dental drill, and the other 2, which virtually defied cutting, by aspirating the corpus cavernosum following degloving surgery. CONCLUSION: In removing foreign objects around the penis, simpler methods should be given precedence over more complex ones, and for those that virtually defy cutting, the best option is degloving surgery with particular attention to the survival of the penile skin flap.

[Relationship between the intrapelvic perfusion pressure in minimally invasive percutaneous nephrolithotomy and postoperative recovery].

OBJECTIVES: To introduce the method to monitor intrapelvic perfusion pressure during minimally invasive percutaneous nephrolithotomy (MPCNL), and to observe the effect of high pressure intrapelvic perfusion on recovery. METHODS: The end of F5 ureteral catheter and aseptic transducer were connected by self-made connecter. During the operation, 46 renal calculi cases were monitored, and the early complication, such as fever, pain index, drop of hemoglobin, the stone-free rate and hospital stay were investigated. And the relationship between the variation of pressure and recovery was studied. RESULTS: Intrapelvic perfusion pressure ranged from 3 mm Hg (1 mm Hg = 0.133 kPa) to 50 mm Hg during the course of MPCNL. The definition of high pressure was the time of the pressure more than 30 mm Hg not less than 10 min. Postoperative fever rate, pain index, drop of hemoglobin and hospital stay in the high pressure were significantly higher than low pressure group (P< or =0.05). There was no difference of the stone-free rate in two groups. CONCLUSIONS: During the course of MPCNL intrapelvic perfusion pressure should be monitor immediately. It should be careful to maintain the time of pressure more than 30 mm Hg less than 10 min for stable postoperative recovery.

[Detection of DD3 mRNA in the urine of prostate cancer patients and its clinical significance].

OBJECTIVE: To detect the differential display code 3 mRNA (DD3 mRNA) in the urine sample of patients with prostate cancer and to evaluate its clinical significance. METHODS: DD3 mRNA in the urine collected from 48 patients with prostate cancer, 23 patients with benign prostate hyperplasia (BPH) and 9 healthy male volunteers was measured by reverse transcriptase polymerase chain reaction (RT-PCR). RESULTS: DD3 products could not be detected in the urine samples of the BPH patients and healthy male volunteers, but could in 39/48 urine samples of the patients with prostate cancer. Significant difference was found between them (P < 0.01). CONCLUSION: The detection of DD3 mRNA in the urine promises to be a non-invasive, simple and sensitive method for the early diagnosis and post-treatment monitoring of prostate cancer.

[Clinical investigation of the treatment of children urethral calculi with pneumatic lithotripsy under ureteroscopy].

OBJECTIVE: To evaluate the therapeutic effects of pneumatic lithotripsy on children urethral calculi. METHODS: Twenty-two cases of the male children with urethral calculi were treated with pneumatic lithotripsy under ureteroscopy. RESULTS: All the patients were treated successfully in a single procedure. The time of lithotripsy was (5.5 +/- 2.2) minutes, and no serious complication such as obvious hematuria, infection and urethral stricture occurred. CONCLUSIONS: It is suggested that pneumatic lithotripsy under ureteroscopy is an effective and simple way for the treatment of urethral calculi in children.
