ABSTRACT
【Objective】 To investigate the application of different ureteral length measurement methods in the indwelling of double-J stent. 【Methods】 Clinical data of 260 patients with double-J stent indwelling after ureteroscopic surgery during Jul.2018 and Dec.2020 were prospectively analyzed. The patients were randomly divided into height calculation group, CT measurement group, KUB group and ureteroscopic measurement group. The length of ureter was calculated accordingly and the appropriate length of double-J stent was selected. KUB was performed on the first day after operation and before extubation to determine the position of double-J stent. The patients completed the ureteral stent-related symptom questionnaire (USSQ), urinary symptom score, lower urinary tract symptom (LUTS) score, pain score, hematuria score, and quality of life score before and after double-J catheter placement. 【Results】 There were no significant differences in age, gender, height, side of stent and urinary symptom score among the four groups (P>0.05). The average lengths of the ureters measured by the four methods were (21.5±1.0) cm, (21.5±1.8) cm, (23.8±1.3) cm and (21.7±1.8) cm, respectively. There were no significant differences among the height calculation group, CT measurement group and ureteroscope group, but there was significant difference between the three groups and the KUB group. The ideal ureteral stent length indwelling ratio in the ureteroscopic group was 76.9%, which was better than that in the other three groups. Postoperative indwelling time was 7-42 d (mean 29.8 d). The USSQ score of the ureteroscopic group before extubation was (14.1±1.5), which was lower than that of the other three groups (P<0.05). The ureteroscopic group was better than the other three groups in the comparison of frequency and urgency of urination, nocturia, hematuria, quality of life score, and pain score (P<0.05). 【Conclusion】 Intraoperative ureteroscopic measurement of the ureteral length is a simple and feasible method in guiding the indwelling of double-J stent to reduce ureteral stent related symptoms.
ABSTRACT
Objective To investigate the histologic characteristics of small -size prostatic hyperplasia (SBPH)and the effect on low urinary tract symptoms (LUTS).Methods 154 patients with SBPH who received transurethral resection of prostate (TURP) were enrolled,preoperative examinations included the obtainment of International Prostate Symptom Score(IPSS),evaluation of the quality of life(QOL),cases of urinary retention,ultra-sonography,urodynamic examination,and cystoscopy,postoperative pathology specimen analysis was conducted.The histologic characteristics of small -size prostatic hyperplasia(the histology prostatis and the grade of inflammation) and the effect on LUTS were analyzed.Results A total of 141 cases (91.56%)were diagnosed as SBPH with histo-logical prostatitis,13 cases(8.44%)in grade 0,18 cases(11.69%)in grade 1,76 cases(49.35%)in grade 2 and 47 cases(30.52%)in grade 3.There were statistically significant differences among ages,IPSS,QOL,Qmax,cases of urinary retention between the pure SBPH group and SBPH with HP group(t/χ2 =2.610,6.607,4.925,2.673, 4.421,all P 0.05).Conclusion The main pathologic type is stroma hyperplasia(fibrous and smooth muscle)of SBPH,SBPH is mostly complicated with histological prostatitis,which are mostly moderate and severe.The severity of LUTS is positively correlated with the grade of inflammation.
