Objective@#To observe the analgesic and sedative effect of epidural dexmedetomidine injection in patients undergoing transurethral resection of prostate (TURP) and its effect on postoperative cognitive function.@*Methods@#A total of 60 patients undergoing TURP under combined spinal-epidural anesthesia (CSEA) were randomly divided into dexmedetomidine group and normal saline group. Patients in the dexmedetomidine group were given 0.1 μg/kg of dexmedetomidine injection after epidural anesthesia, and 0.9 μg/kg of dexmedetomidine was added into epidural analgesia pump after operation; patients in the normal saline group were given the same dose of normal saline. The vital signs, visual analogue scale (VAS) and Ramsay sedation score of patients in the two groups at different time points[before intervention (T0), after intervention for 15 min (T1), after intervention for 30 min (T2), after intervention for 45 min (T3), after intervention for 60 min (T4), after surgery for 12 h (T5), after surgery for 36 h (T6)] were recorded.

Objective To explore the availability and safety of conducting low-pressure TURP assisted by a home-made cystometry and warning system.Methods 167 benign prostatic hyperplasia (BPH) patients admitted from Jan 2014 to Jan 2016 were randomly assigned into cystostomy group (group A) and non-cystostomy group (group B). In group A (n = 85), 42 patients (group A1) were performed percutaneous cystostomy + TURP, and 43 (group A2) were performed continuous flushing sheath TURP. In group B (n = 82), 42 patients (group B1) were received percutaneous cystostomy + TURP, and 40 (group B2) were received continuous lfushing sheath TURP. In group A, bladder pressure was monitored in real time with a cystometry and was monitored by bladder puncture using a home-made siphon, ensuring low bladder pressure throughout TURP. Serum Na+ levels were measured before and after operation in all four groups. The operation time, the intraoperative bleeding, the weight of resected prostates and the time before which urine turned clear were recorded. The IPSS, maximum lfow rate (Qmax), postvoid residual volume (PVR) and life quality score (QOL) were evaluated.Results While no significant differences were found between group A1 and A2, there were significant differences between group B1 and B2, indicating cystostomy group was safer than non-cystostomy group. When compared group A1 with B1, or group A2 with B2, it showed that the safe operation time to perform prostate tissue resection was longer in cystostomy group; the weight of the resected prostates was heavier; the time before which urine turned clear were shorter; and the IPSS improvement was better. These findings presented better therapeutic effects in cystostomy group than in non-cystostomy group.Conclusions This home-made cystometry and warning system could timely detect high bladder pressure state during TURP, making it possible to avoid of high pressure, ensuring low bladder pressure lfushing during the operation, lengthening the safe operation time, increasing tissue resection ratio, reducing transurethral resection syndrome, thus helping TURP to be safer.

Objective To investigate the clinical efficacy of modified YV-plasty for refractory bladder neck contracture (BNC) caused by transurethral resection of prostate (TURP).Methods From June 2013 to March 2016,11 patients with BNCs secondary to TURP were included in this study.Their mean age was 63.7 years (range,56-73 years).All patients presented voiding difficulty and failed after 2 or more prior endoscopic treatments.Modified YV-reconstruction of bladder neck was performed,by incising the anterior wall of bladder neck in a T-shaped manner,and creating two well-vascularized and tension-free flaps,which offer the possibility to reconstruct a wide bladder neck.Results After a mean follow-up of 14.6 months (ranging 3-24 months),successful outcome was achieved in 9 patients without incontinence secondary by surgery.Recurrent voiding difficulty developed in 2 patients,which was cured after a following endoscopic treatment.Conclusion A wider bladder neck can be obtained through modified YV-reconstruction of bladder neck,while avoiding external urethral sphincter injury.It is an available option for refractory bladder neck contracture.

Objective To investigate the causes,treatments,and prevention of dysuria after transurethral resection of prostate (TURP). Methods The clinical data of 49 cases of dysuria post-TURP that were treated in our hospital from July 2004 to September 2008 were analyzed retrospectively. Results Among the cases,6 patients received silica catheterization again because of edema of the bladder neck and urethra; 9 underwent catheterization after bladder flush for delayed prostate bleeding; 20 underwent urethral dilatation or meatotomy due to meatal stenosis,5 received urethral dilatation for urethral stricture; urethral dilatation or direct vision internal urethrotomy were performed on 4 cases who had bladder neck fracture; TURP was carried out for a second time in 4 cases because of glandular residual; suprapubic cystostomy was made in 1 case of colonal carcinoma for long-term bed rest. All cases were cured after the treatment. Conclusions Meatal stenosis is the most common cause of dysuria post-TURP.Urethral dilatation is the first choice for the disease.
Résumé
BACKGROUND: The combination of local anesthetics and opioids in the spinal anesthesia has a synergic analgesic effect. Therefore, we compared intraoperative conditions and clinical effects of low dose (5 mg) bupivacaine added with fentanyl versus a conventional dose(10 mg) of bupivacaine in spinal anesthesia for a transurethral resection of the prostate (TURP). METHODS: Forty five ASA class 1 and 2 patients scheduled for a TURP were randomly divided into three groups. Group B (n = 15) received bupivacaine 10 mg, group BF (n = 15) received bupivacaine 5 mg added with fentanyl 20microgram, and group BFE received bupivacaine 5 mg added with fentanyl 20microgram and 0.2 mg epinephrine. Blood pressure and heart rate were recorded every 5 minutes before and after spinal anesthesia. Sensory blockade was measured by a pin-prick test and motor blockade was evaluated by the Bromage motor scale. Side effects including pruritus, nausea, vomiting, respiratory depression, and intraoperative pain were observed. RESULTS: The duration of sensory and motor blockade in group BF was significantly shorter than in group B and group BFE (P<0.05). Without statistical significance, hypotension (6.7%) and bradycardia (13.3%) were observed in group B and pruritus (26.7%) and nausea (13.3%) occurred in all patients who received fentanyl. CONCLUSIONS: The addition of fentanyl 20microgram to low dose bupivacaine 5 mg resulted in short lasting motor and sensory block, compared with conventional dose bupivacaine 10 mg. Therefore, we concluded that the clinical application of this method could provide adequate analgesia with early discharge and no serious side effects for TURP patients.
