Clinical application of partial cystectomy with augmentation cystoplasty for invasive bladder cancer in elderly patients / 北京大学学报(医学版)

ABSTRACT

OBJECTIVE@#To evaluate the clinical effect and safety of biological patch applied in elderly patients with invasive bladder cancer who underwent massive partial cystectomy with augmentation cystoplasty.@*METHODS@#The clinical data of 2 patients with invasive bladder cancer from October 2016 to March 2017, who underwent the massive partial cystectomy with augmentation cystoplasty were retrospectively reviewed. Case one was an 87-year-old man, with tumor located on the bladder anterior wall, ranging from 5.5 cm×2.5 cm, and the grade of American Society of Anesthesiologists (ASA) being III. Case two was a 77-year-old female, whose lesion was located on the right anterior wall, ranging from 5.2 cm×4.0 cm, and the grade of ASA being II. Both of the patients received a massive partial cystectomy with augmentation cystoplasty. The operative time, estimated blood loss, perioperative and postoperative data and follow-up data, including cystoscopy and urodynamics were recorded and compared. When the P value was less than 0.05, it was statistically significant.@*RESULTS@#All the operations were successfully performed. The average operative time was (155.0+35.4) min, mean estimated intraoperative blood loss was 20 to 100 mL, and the mean postoperatively hospital stay was eight days. During the 10 to 14 months' follow-up periods, no local recurrence or distant metastasis occurred. Urodynamic data: the maximum urinary flow rate was 16.5 mL/s, and the maximum bladder capacity was 303 mL. The two patients urinated 3-4 times in the day time, 0 to 3 times in the night, 200-300 mL each time, on average. The American Urological Association symptom score was 3 to 5. Partial cystectomy, applied to aged patients with multiple complications and high risk of surgical anesthesia, was able to reduce surgery related complications. For patients with tumor of small size, the normal bladder wall would be enough to recover functional capacity for urine storing after partial cystectomy. For patients with large lesions range and small normal bladder tissues, augmentation cystoplasty would help recover bladder capacity on the condition of negative margin.@*CONCLUSION@#Massive partial cystectomy with augmentation cystoplasty is safe and effective. It could decrease perioperative morbidity and keep the quality-of-life benefits of bladder preservation, which is worthy of further application for some selected invasive bladder cancer in elderly patients.
