Objective:To explore the long-term efficacy of a modified unilateral cutaneous ureterostomy in bladder cancer patients receiving radical cystectomy.Methods:The medical data of 104 bladder cancer patients who underwent ureterostomy in our hospital from Janurary 2013 to December 2020 were retrospectively analyzed. The patients were divided into unilateral and bilateral group. The unilateral group contained 66 cases, with 53 males and 13 females, average age (71.8±9.8) years, body mass index (BMI)(23.3±3.2)kg/m 2. The bilateral group contained 38 cases, with 33 males and 5 females, average age (75.1±10.8) years; BMI (22.7±3.0)kg/m 2. There was no significant difference in the above characteristics between the two groups ( P>0.05). The pathology, survival status, long-term complications between the two groups were compared. Quality of life was assessed during follow-up using the European Core Questionnaire for Quality of Life in Cancer Patients (EORTC QLQ-C30). Results:The unilateral group contained 46(69.7%) muscle invasive bladder cancer (MIBC) cases, 15 (22.7%) cases with lymph node metastasis, 7 (10.6%) cases with distant metastasis. The bilateral group contained 24(63.2%) muscle invasive bladder cancer(MIBC) cases, 6 (15.8%) cases with lymph node metastasis, 2 (5.3%) cases with distant metastasis. There was no significant difference in disease specific survival between the two groups ( P>0.05). During the follow-up, the incidence of overall complication rate in the unilateral group was significantly lower than that in the bilateral group [43.9% (29/66) vs. 63.2% (24/38), P<0.001]. The incidence of pyelonephritis in unilateral group was significantly lower than that in the bilateral group [16.6%(11/66) vs. 42.1%(16/38), P=0.006]. There was no statistical significance in terms of quality of life before operation in the two groups. After operation, both physical function score[(54.9±7.1) vs.(49.2±6.7)] and emotional function score [(63.1±6.4) vs.(59.9±6.7)] in unilateral group were higher than that in bilateral group ( P<0.05). Conclusions:The modified unilateral cutaneous ureterostomy could achieve relatively low complication rate, and improve the quality of life to some extent compared with bilateral ureterostomy.

Objective:To investigate the effectiveness of surgical treatment for patients with T 4 stage prostate cancer. Methods:The clinical data and prognosis of 18 patients with T 4 stage prostate cancer treated in Shanghai Tenth People's Hospital from July 2013 to December 2019 were retrospectively analyzed. The average age of these 18 patients was 68.3 (53-81)years. 10 patients were castration resistant prostate cancer (CRPC) and 8 patients were hormone-sensitive prostate cancer (HSPC). 10 CRPC patients were treated with surgical treatment due to bladder clot packing and/or lower urinary tract obstruction. 8 HSPC patients had severe hematuria, severe dysuria and local symptoms. The KPS scores of all patients were ≥80 points with an average score of 84 (80-90). The average QOL score of 18 patients was 28 (21-32). 2 cases in 18 patients underwent total pelvic resection for rectal invasion (one CRPC and one HSPC). 7 cases underwent radical cystoprostatectomy for ureteral invasion (5 cases of CRPC, 2 cases of HSPC), 9 cases underwent bladder preservation surgery for bladder neck invasion (4 cases of CRPC, 5 cases of HSPC), of which 4 cases of enlarged lymph node dissection were all HSPC patients. Results:All cases of T 4 stage prostate cancer patients operation were successfully completed, the average operation time was 256 (219-310)min and the median intraoperative blood loss was about 300 (250-350)ml. Four of them (3 cases of CRPC and 1 case of HSPC) received blood transfusion after operation. The average postoperative hospital stay was 21(11-37) days. All 18 cases were followed up and the median follow-up time was 23.8 months. There was no perioperative death, and no bladder-preserving patients had true urinary incontinence or bladder outlet stenosis.2 CRPC cases died 8 and 15 months after surgery respectively, 7 patients were PSA relapse treated with docetaxel or abiterone therapy, and 1 HSPC patient with rectal invasion was followed up for 58 months after total pelvic resection, the PSA level was still 0.003ng/ml, no distant metastasis was found. 8 cases of hormone-sensitive patients were treated with endocrine therapy, and PSA was less than 0.2 ng/ml. The average QOL of 18 patients 3 months after operation was 37 points (25-45), which was significantly higher than that before operation. The average maximum urine flow rate of patients with bladder preservation was 23(19-25)ml/s. Conclusions:For T 4 stage prostate cancer, surgical treatment is feasible and safe for doctors with extensive surgical experience. For CRPC patients, the surgery can significantly improve short-term symptoms and quality of life, and long-term benefits need to be further evaluated with a large sample. For HSPC patients, it can not only improve clinical symptoms and QOL of patients, but also provide long-term benefits.

<p><b>BACKGROUND</b>Most of the literatures on laparoscopic partial nephrectomy (LPN) versus open partial nephrectomy (OPN) focus on technical details and early or mid-term oncologic outcomes, reflecting that the approach is safe and provides midterm benefits compared with traditional open surgery. However, the difference of long-term oncologic outcome between LPN and OPN remains unclear. The aim of this meta-analysis was to evaluate the long-term oncologic outcome of LPN in the treatment of localized renal tumors compared with that of OPN.</p><p><b>METHODS</b>A systematic search of electronic databases including Medline, Embase, and Cochrane library was conducted. Comparative studies reporting on long-term oncologic outcome of LPN versus OPN were regarded eligible. The odds ratio (OR) and its corresponding 95% confidence intervals (CI) were calculated for the oncologic outcomes. The methodologic quality of the included studies was evaluated using the strict criteria of the Newcastle-Ottawa scale.</p><p><b>RESULTS</b>Six comparative studies (1495 participants including 555 LPN and 940 OPN) were included in the present study. There was no significant difference between LPN and OPN in 5-year overall survival (OS) rates (OR = 1.83, 95% CI (0.80, 4.19)), 5-year cancer specific survival (CSS) rates (OR = 1.09, 95% CI (0.62, 1.92)), and 5-year recurrence free survival (RFS) rates (OR = 0.68, 95% CI (0.37, 1.26)).</p><p><b>CONCLUSION</b>The results of this meta-analysis revealed that there was no significant difference in long-term oncologic outcome between LPN and OPN for treatment of localized renal tumors.</p>

Objective To evaluate the value of sonourethrography in the diagnosis of dysuria after bipolar transurethral plasmakinetic prostatectomy. Methods Sixty male patients with dysuria after bipolar transurethral plasmakinetic prostatectomy underwent sonourethrography and re-operation.The clinical data of these patients were reviewed. Results The sonourethrographic findings were similar with the operative findings in 57 cases.In the 60 cases,there were 11 cases with bladder neck closure,10 cases with bladder neck stricture,30 cases with urethral stricture (16 located at membranous urethra,12 located at pars cavernosa urethra and 2 in external orifice of urethra),5 cases with prostate remnant,1 case with calculi in prostatic urethra,2 cases with dysfunction of detrusor of bladder and 1 case with flap of internal urethral orifice,Conclusions Sonourethrography could be a reliable diagnostic method for dysuria after bipolar transurethral plasmakinetic prostatectomy.It may be helpful for clinical treatment.
