RESUMO
Objective To investigate the management and prevention of the complications of sigmoid rectal pouch for urinary division after radical cystectomy. Methods The clinical data of 34 patients who underwent a sigmoid rectal pouch procedure were analyzed retrospectively, and the clinical experience was summarized in the management and prevention of the complications of sigmoid rectal pouch for diversion. Results Twenty-six patients were followed up for 2 months to 11 years, and 10 patients lost in follow-up. The early follow-up results were as follows:3 patients had postoperative high fever with unilateral the kidney water, 1 patient had retropubic bleeding and need to stop bleeding, 3 patients suffered from wound split open and were performed relaxation suture, and 1 patient had sigmoid colon rectum bladder fistula 10d after operation. The late follow-up results were as follows:1 patient had urethral neoplasms recurrence, 5 patients developed distance metastases, and 5 patients developed nocturnal incontinence and worn safety pad. There were no hyperchloremic acidosis requiring clinical treatment, hydronephrosis as well as retrograde pelvis infection. Conclusions The operation of sigmoid rectal pouch for urinary division is fairly simple, with no serious complication. It is a better alternative diversion procedure, and should be accepted gradually by patients and surgeons.
RESUMO
Objective To investigate the feasibility and efficacy of transurethral prostate enucleation with 2 μm laser in the treatment of benign prostatic hyperplasia (BPH). Methods One hundred and seven patients with BPH were treated by transurethral prostate enucleation with 2 μm laser under continuous epidural anesthesia or laryngeal mask anesthesia. The patient′s, average age was 67±9 yrs (52 to 85 yrs). Of whom, 10 patients had a history of urinary retention. The mean prostate volume was 72.5±17.6 ml (45 to 158 ml). Two deep trenches were cut at the 5 and 7 o, clock position from the bladder neck to the verumontanum. The incision continued to the urethral mucosa and submucosa along with the verumontanum bilaterally in an arc-shape and ended at the internal arc of urethral sphincter. Then the urethral mucosa at the level of the verumontanum was cut and the surgical capsule plane was identified. A retrograde blunt dissection was made along the surgical capsule plane with the resectoscope sheath front-end, and the sheath was swung from side to side to extend the capsule plane. The significantly enlarged middle lobe was treated with laser vaporization resection. In the same way, a trench was made at the 12 o, clock position, and the lateral lobe were removed by the sheath from the verumontanum level, finally only two cord-like pedicles were kept at the 1 and 11 o, clock position at the bladder neck, so that the removed gland tissue was fixed and hung in the gland fossa. For prostate volume less than 60 ml, the laser vaporization resection was carried out directly. If the prostate volume was greater than 60ml, transurethral resection would be performed instead of laser vaporization resection. With 4% mannitol irrigation, the enucleated prostate tissue was then cut into small pieces and washed out by a Braun plastic bottle through the resectoscope sheath. Intraoperative bleeding, operative time, catheterization time, postoperative voiding status, maximum urinary flow rate (Qmax) and length of hospital stay were recorded and analyzed. Results All patients successfully completed the transurethral prostate enucleation. The average operative time was 74±12 min (45-150 min). Five cases required blood transfusion. There was no recorded urethral stricture and no urinary incontinence except for one patient who recovered 1 mon after the operation. The follow-up time was 2-6 mon. The average Qmax was 6.3±0.6 ml/s before and increased to 17.5±1.5 ml/s after the operation. The international prostate symptom score (IPSS) and quality of life (QOL) were reduced from 26.4±5.5 and 4.6±0.5 to 9.3±2.1 and 2.8±0.3 after the operation, respectively, P<0.01. Postoperative secondary bleeding was not observed. Conclusions Transurethral prostate enucleation with 2 μm laser for BPH is a safe and effective minimally invasive treatment. Its efficacy is superior to open surgery, and even better than TURP.
