Diagnosis and selection of surgical treatment of paraurethral cyst in adults / 现代泌尿外科杂志

【Objective】 To explore the diagnosis and choice of surgical treatment of paraurethral cyst in adults. 【Methods】 The clinical data of 56 patients with paraurethral cyst treated at our hospital during Dec.2011 and Jul.2022 were retrospectively analyzed. 【Results】 Of the 56 patients, most of the urethral masses were found during physical examination or bathing, and the time between finding of masses and admission was 2 days to 10 years. Two cases were diagnosed as vaginal wall mass, and one as ureal mass, which were confirmed by postoperative pathology as leiomyoma. Fifty-three cases were diagnosed as paraurethral cysts, 15 of whom underwent fenestration and 38 complete resection of the cyst wall. In the 38 cases who underwent complete resection of cyst wall, 6 had urethral damage due to large and deep cysts closely connected with the urethra, and catheter was indwelled for 10 to 14 days after surgery. All cases were cured without complications. There was no recurrence during the 2 months to 10 years of follow-up. 【Conclusion】 Paraurethral cysts are not difficult to diagnose. Large cysts are likely to damage the urethra due to repeated infection and close connection with urethra. We suggest that the large and deep paraurethral cysts should be removed with fenestration.

Clinical analysis of human acellular allogeneic dermis in the repair of urinary fistula / 现代泌尿外科杂志

【Objective】 To investigate the clinical efficacy of human acellular allogeneic dermis (HADM) in the repair of urinary fistula. 【Methods】 The clinical data of 12 female patients with complex vesicovaginal fistula treated during Jun.2021 and Nov.2022 were retrospectively analyzed. The patients’ average age was 47.3 years, ranging from 38 to 56 years. The body mass index (BMI) ranged from 16.6 to 25.2, with an average of 21.3. HADM was inserted between vagina and bladder wall fistula to repair fistula in all 12 patients. 【Results】 All operations were successful. After the operation, the vaginal urine leakage stopped and the urinary tube was retained for 2 weeks. During the postoperative follow-up of 1 to 16 months, no recurrence or complication were observed. 【Conclusion】 Transvaginal HDMA is an ideal surgical method in the treatment of complex vesicovaginal fistula, which has advantages of small trauma, fast recovery and high success rate.

Clinical analysis of female urethral diverticulum resection and reconstruction under Jacknife position / 中华泌尿外科杂志

Objective To explore the clinical efficacy of female urethral diverticulum resection and reconstruction under the folding position.Methods Retrospective analysis of 22 female patients with urethral diverticulum was performed from September 2010 to December 2018.There were 12 cases of simple diverticulum,6 cases of horseshoe diverticulum,4 cases of circumferential diverticulum,aged from 26 to 72 years,with an average of 46.2 years,whose BMI ranged from 24.2 to 34.8 kg/m2,with an average of 30.4 kg/m2.Eleven cases (50％) presented with dysuria,10 cases (45.5％) with repeated urinary tract infections,7 cases (31.2％) with difficulty of voiding,10 cases (45.5％) with urethral secretion,9 cases (40.1％) with difficulty of sexual intercourse,and 4 cases (18.2％) without symptoms.Unlike the traditional surgical procedure under the lithotomy position,the folding position was used to expose the vagina and separate the vaginal mucosa by longitudinal incision,and the diverticulum was completely removed to the neck.The peri-operative complications and efficacy were recorded.Results All 22 cases underwent successful procedures,and were followed up for 25.2 months on average (ranged 8 to 42 months).One of them suffered from weak stream 2 months after operation,with residual urine volume of 100ml by ultrasonography.Her symptoms improved after dilatation of the urethra.Two cases suffered from different degrees of lower urinary tract storage symptoms 1 month after the operation (1 case of mild dysuria and 1 case of urinary tract infection),who improved after oral administration of levofloxacin tablets for 3-5 days.All patients had no urethral diverticulum recurrence 3 months later by ultrasonography,half a year by cystoscopy,and every six months by ultrasonography.Conclusions Surgical treatment is still the best choice for patients with urethral diverticulum.The success rate of transvaginal urethral diverticulum reconstruction with a Jackknife position is high,postoperative recurrence rate is low,and postoperative complications are few.

Clinical research about needle-tract assisted standard percutaneous nephrolithotomy for the treatment of complicated upper urinary tract calculi / 中华外科杂志

Objective@#To investigate the safety and efficacy of needle-tract assisted standard percutaneous nephrolithotomy (PCNL) for the treatment of complicated upper urinary tract calculi.@*Methods@#The clinical data of 1 562 patients with complicated upper urinary calculi who received standard PCNL from December 2013 to December 2017 at Department of Urology, the First Affiliated Hospital of Xiamen University were retrospectively analyzed. There were large residual stones in 256 patients through B-ultrasound exploration after standard PCNL, could′t be detected with nephoscope in standard PCNL tracts. 16 F mini PCNL tract were established in 120 cases for treatment of residual stones, while needle-tract were established in order to guide nephroscope to find residual stones in 126 cases. Needle-tract were transferred to 16 F mini PCNL tract for treatment of residual stones in 10 patients if these residual stones could′t be detected through needle-tract. Operation time, change of hemoglobin level after operation, incidence of postoperative complications, time of hospitalization and rate of stone clearance were measured in two groups. The statistical methods used included t test, Wilcoxon rank sum test, and χ2 test.@*Results@#There were 1 to 3 mini tracts (M(QR): 1(1)) established in the mini tracts group and 1 to 7 needle-tracts (M(QR): 3(2)) established in the needle-tract group (Z=-10.57, P=0.000). Compared with mini tract group, the operation time ((62.0±18.0) minutes vs. (84.0±15.5) minutes, t=10.242, P=0.000), hospitalization time ((4.40±0.86) days vs. (5.20±0.81) days, t=7.570, P=0.049), hemoglobin dropped ((1.31±0.47) g/L vs. (2.74±0.63) g/L, t=20.12, P=0.000), and incidence of postoperative complications (7.9% (10/126) vs. 19.2% (23/120), χ2=6.674, P=0.01) of needle-tract group were lower, while postoperative stone clearance rate was higher (89.7% vs. 76.7%, χ2=7.497, P=0.006). No perioperative severe complications such as pleural injury, pneumatothorax, perforation of renal, trauma of abdominal organ occurred in two groups.@*Conclusion@#Needle-tract assisted standard PCNL for the treatment of complicated upper urinary calculi can significantly improve stone clearance rate, reduce operation time, decrease risk of kidney and surrounding organs damage.

Inflammatory cells infiltration status in bladder submucosa of patients with cystitis glandularis and its clinical significance / 中华泌尿外科杂志

Objective To analyze the infiltration of inflammatory cells under the mucosa of female cystitis glandularis and the different inflammatory infiltration in different clinical pathological types of cystitis glandularis.Methods Immunohistochemical method was used to detect the bladder mucosal tissue samples of 10 female patients confirmed cystitis glandularis admitted from June 2016 to October 2016.The results of immunohistochemical staining were collected and statistically analyzed by the automatic microscopy and image analysis system.In addition,the clinical data and tissue sample of 49 cases of cystitis glandularis treated from December 2006 to August 2017 were collected.Age of 49 patients was (34.4 ±7.5) years old and BMI was (21.9 ± 4.2) kg/m2.There were 19 cases of hypertension and 18 cases of diabetes.According to the cystoscopic manifestations,follicular edema type,papilloma type,and intestinal adenomatosis type were defined as high risk.Chronic inflammatory type and mucosa unchanged type were defined as low risk.Immunohistochemical staining was used to detect tissue samples,to compare the general data of different types of cystitis glandularis and the degree of infiltration of bladder mucosal inflammatory cells.Results T lymphocytes were highly expressed in 10 patients,and B lymphocytes and plasma cells were not expressed or extremely low (P ＜ 0.01).Of the 49 patients,29 were high risk type cystitis glandularis (follicular edema type,papilloma type,and intestinal adenomatosis type),and 21 were low risk type (chronic inflammatory type and mucosa unchanged type).The age of the high-risk group was (34.4 ± 7.5) years old with BMI of (21.9 ±4.2) kg/m2,8 cases of hypertension and 8 cases of diabetes.The age of the low-risk group was (38.2 ±8.5) years old with BMI of (20.8 ±4.0) kg/m2,11 cases of hypertension and 10 cases of diabetes.There was no statistically significant difference between two groups (P ＞ 0.05).The OABSS of high-risk group(10.4 ± 2.6) was significantly higher than that of low-risk group (7.1 ± 2.1,P ＜ 0.01).QOL of high-risk group (4.9 ± 0.9) was significantly higher than that of low-risk group (4.1 ± 0.8,P ＜ 0.01).Qmax of high-risk group was (11.4 ± 3.6) ml/s,significantly lower than that of low-risk group[(15.8 ±3.8) ml/s,P ＜0.01].The positive number of T lymphocytes of high-risk group was (173.5 ± 26.8),which was significantly higher than that of low-risk group(119.5 ± 21.2,P ＜ 0.01).Conclusions T lymphocytes infiltration is the major phenomenon in bladder submucosa of female patients with cystitis glandularis.The inflammatory infiltration by T lymphocytes could be associated with patient's symptom and bladder's pathological changes.
