ABSTRACT
Objective:To collect data on urinary flow rate in the elderly female population across the country and to analyze the range of reference values.Methods:This study enrolled 333 subjects from July 2020 to June 2022.The study implementation process was divided into two steps.In the first step, subjects completed an electronic questionnaire, which included basic information about the subject, a short form for urinary incontinence, and a scoring form for the symptoms of overactive bladder syndrome.In the second step, the staff introduced the use of a mobile uroflowmetric device and distributed the instrument and materials.Uroflow rate data were automatically uploaded to a cloud database via the mobile phone.Subsequently, two or more physicians specializing in urinary control performed Uroflow rate-qualifying screenings and conducted statistical analyses.Results:A total of 333 subjects were enrolled in the study, and the researchers collected 1375 qualified urine flow rate records using a mobile urine flow rate instrument.The age of the subjects ranged from 60 to 84 years, with a mean age of 69 years.The reference ranges for urinary flow rate were found to be 24.8-26.2 s, with a mean urinary flow rate of 12.2-12.9 ml/s, a maximum urinary flow rate of 22.2-23.4 ml/s, and a time to peak of 8.5-9.7 s. The study observed a tendency for both maximal and mean urinary flow rates to decrease in older women as their age increased(Pearson correlation coefficient: -0.1, P<0.001). Conclusions:The uroflow rate of older women decreases with aging.Specifically, the average uroflow rate of women over 80 years old is lower than that of other age groups.This study aims to establish normal uroflow parameters for uroflowmetry in healthy older women in China.
ABSTRACT
Objective:To explore the effect of fecal microbiota transplantation (FMT) on the formation of renal calcium oxalate crystals in SD rats induced by oxalate mixed diet.Methods:Six male guinea pigs were fed with standard guinea pig chow for 1 month and then given a 5% oxalate diet for 14 d. The guinea pigs on the standard chow were labeled as the standard chow guinea pig (GSC group) and those on the high oxalate diet for 14 d were labeled as the guinea pig group on the high oxalate diet (GOD group). The feces of guinea pigs in the GSC and GOD groups were collected using metabolic cages. Twenty-four male SD rats were randomly divided into standard chow (SC) group, oxalate diet(OD)+ phosphate buffered saline gavage group (OD+ PBS group), OD+ FMT group and SC+ FMT group. Among them, the SC group and SC+ FMT group were fed with standard chow. The OD+ PBS group and OD+ FMT group were fed with 5% oxalate content chow. The OD+ FMT and SC+ FMT groups were given GOD group guinea pig fecal filtrate gavage for 7 days. The 24 h urine and feces of rats in each group were collected, and the intestinal microbiota of rats and guinea pigs were detected by 16sRNA detection. The urinary oxalate excretion was detected by high performance liquid chromatography. The rats and kidneys were weighed and the renal index was calculated. HE staining was used to observe the histological morphological changes of rat kidney tissue, the calcium oxalate crystal deposition in renal tissues was detected by Pizzolato staining.Results:The relative abundance of bacteria from a total of 11 families, including Muribaculaceae family and Bifidobacteriaceae family, was significantly increased in the intestinal tract of guinea pigs (GOD) from the high oxalate diet group compared to guinea pigs (GSC) from the standard chow group. The microbial diversity of the intestinal microbiota of the rats in the OD+ PBS group was reduced compared to the SC group, and the microbial diversity of the intestinal microbiota of the rats in the OD+ FMT group was restored compared to the OD+ PBS group. When given a standard chow, the intestinal microbiota of rats receiving FMT deviated from that of normal rats and was more similar to that of guinea pigs fed a high oxalate diet. In the OD+ FMT group, bacteria from a total of 18 families, including Muribaculaceae family, Erysipelotrichaceae family and Bifidobacteriaceae family, were significantly enriched, and FMT activated the intestinal microbial network represented by bacteria from Muribaculaceae family. The renal index of rats in the OD+ PBS group was significantly increased compared to the SC group (7.63±0.67 vs. 6.12±0.53, P<0.05), whereas the renal index of rats in the OD+ FMT group was significantly decreased in comparison to the OD+ PBS group (6.53±0.64 vs. 7.63±0.67, P<0.05). Urinary oxalate excretion of rats in the SC group, the OD+ PBS group, and the OD+ FMT group were (0.61±0.05), (0.89±0.04) and (0.72±0.04) μmol/ml, respectively. In the rats of the SC group no calcium oxalate crystals were seen in the kidney (0 score) and more calcium oxalate crystals were detected in the OD+ PBS group (4.83±0.41 score). The OD+ FMT group showed significantly lower calcium oxalate crystallization scores (3.17 ± 0.75 score, P<0.01) compared to the OD+ PBS group. Conclusions:FMT activated the microbial network represented by bacteria from the family Muribaculaceae in the rat intestine, significantly reduced urinary oxalate excretion and renal calcium oxalate crystal deposition in rats on a high oxalate diet.
ABSTRACT
Objective To evaluate the clinical value of holographic image navigation in urological laparoscopic and robotic surgery.Methods The data of patients were reviewed retrospectively for whom accepted holographic image navigation laparoscopic and robotic surgery from Jan.2019 to Dec.2019 in Beijing United Family Hospital and other 18 medical centers,including 78 cases of renal tumor,2 cases of bladder cancer,2 cases of adrenal gland tumor,1 cases of renal cyst,1 case of prostate cancer,1 case of sweat gland carcinoma with lymph node metastasis,1 case of pelvic metastasis after radical cystectomy.All the patients underwent operations.In the laparoscopic surgery group,there were 27 cases of partial nephrectomy,1 case of radical prostatectomy,2 cases of radical cystectomy and 2 cases of adrenalectomy.In the da Vinci robotic surgery group of 54 cases,there were 51 cases of partial nephrectomy,1 case of retroperitoneal lymph node dissection,1 case of retroperitoneal bilateral renal cyst deroofing and 1 case of resection of pelvic metastasis.There were 41 partial nephrectomy patients with available clinical data for statistic,with a median age of 53.5 years (range 24-76),including 26 males and 15 females.The median R.E.N.A.L score was 7.8 (range 4-11).Before the operation,the engineers established the holographic image based on the contrast CT images and reports.The surgeon applied the holographic image for preoperative planning.During the operation,the navigation was achieved by real time fusing holographic images with the laparoscopic surgery images in the screen.Results All the procedures had been complete uneventfully.The holographic images helped surgeon in understanding the visual three-dimension structure and relation of vessels supplying tumor or resection tissue,lymph nodes and nerves.By manipulating the holographic images extracorporeally,the fused image guide surgeons about location vessel,lymph node and other important structure and then facilitate the delicate dissection.For the 41 cases with available clinical data including 23 cases of robotic-assisted partial nephrectomy and 18 cases of laparoscopic nephrectomy,the median operation time was 140 (range 50-225) min,the median warm ischemia time was 23 (range 14-60) min,the median blood loss was 80(range 5-1 200) ml.In the robotic surgery group,the median operation time was 140 (range 50-215)min,the median warm i schemia time was 21 (range 17-40)min,the median blood loss was 150(range 30-1 200)ml.In the laparoscopic surgery group,the median operation time was 160(range 80-225)min,the median warm ischemia time was 25 (range 14-60)min,the median blood loss was 50 (range 5-1 200) ml.All the patients had no adjacent organ injury during operation.There were 2 cases with Clavien Ⅱ complications.One required transfusion and the other one suffered hematoma post-operation.However,the tumors were located in the renal hilus for these 2 cases and the R.E.N.A.L scores were both 11.Conclusions Holographic image navigation can help location and recognize important anatomic structures during the surgical procedures..This technique will reduce the tissue injury,decrease the complications and improve the success rate of surgery.
ABSTRACT
Objective:The clinical efficacy, safety and quality of life in female patients with stress urinary incontinence (SUI)treated by midurethral sling were studied by multicenter retrospective study.Methods:From January 2018 to December 2018, 531 female patients with severe stress urinary incontinence from seven domestic urinary center were included in this study, including 78 cases from General Hospital of Central Theater Command, 122 cases from Shanghai Jiao tong University School of Medicine Affiliated Ren Ji Hospital, 67 cases from Shanghai Jiaotong University Affiliated First People’s Hospital, 68 cases from People’s Hospital of Jiangsu Province, 71 cases from The First Affiliated Hospital of Xi’an Jiaotong University, 65 cases from Zhejiang Provincial People’s hospital, 60 cases from Xiamen University First Affiliated Hospital. Among the 531 patients, 214 cases received TVT sling with an average age of (58.14±10.16) years. 181 cases were in postmenopausal(84.6%). The number of births ≥2 times was 89 (41.6%) cases. The score of ICI-Q-SF was 16.00±1.73. There were 166 cases of moderate incontinence (77.6%) and 48 cases of severe incontinence (22.4%). There were 317 patients in the TOT/TVT-O group with an average age of (58.33±10.25) years. 247 cases were in postmenopausal(77.9%). The number of births ≥2 times was 120 (37.8%) cases. The score of ICI-Q-SF was 15.79±1.75. There were 256 cases of moderate incontinence (80.8%) and 61 cases of severe incontinence (19.2%). There was no statistically significant difference in general data parameters between the two groups ( P>0.05). 1, 6, 12 months after the operation, the two groups of patients incontinence questionnaire Summary(ICI-Q-SF), common complications and Patient Global Impression of Improvement(PGI-I), satisfaction evaluation follow-up. ICI-Q-SF score improved > by 50% (cure + significant improvement) and 1-hour pad test <10 g (qualitative index) were used as the evaluation index of surgical success. Result:Both of the two surgical methods have high successive rate. There was no significant difference between 94.9% (203/214) of the TVT group and 93.7% (297/317) of the TOT/ TVT-O group ( P>0.05). Postoperative improvement of urinary incontinence (cure rate) [88.3% (189/214)]in the TVT group was slightly higher than that in the TOT/ TVT-O group [77.0% (244/317)] ( P<0.05). There was no change in the recurrence rate of urinary incontinence in the follow-up 6 and 12 months after the operation. There was no statistically significant difference between 4.4% (9/203) in the TVT group and 5.4% (16/297) in the TOT/TVT-O group ( P>0.05). The subjective cure rate 12 months after the operation was 96.3% (206/214) in the TVT group and 95.9% (304/317) in the TOT/TVT-O group ( P>0.05). 10 patients occurred bladder perforation occurred in the TVT group, and no bladder perforation occurred in the TOT/TVT-O group ( P<0.001). The incidence of pain and discomfort in the TVT group was significantly lower at 1.9% than that in the TOT/TVT-O group at 6.9% ( P<0.01). There was no statistically significant difference between the two groups in the incidence of complications such as dysuria/urinary retention, frequent urination/urgency incontinence. Both of them exposed sling ( P>0.05). Conclusion:Both TVT and TOT/TVT-O sling can effectively treat female stress urinary incontinence, and both can improve the sexual satisfaction of patients after the surgery, with fewer complications and other advantages. The selection of specific surgical methods in clinical practice can be individualized according to the patient's physical conditions, clinical needs and the operation methods familiar to doctors.

Objective To investigate the clinical significance of urinary continence after laparoscopic radical prostatectomy with the technique of preserving bladder neck with sling suspension technique by the seminal vesicle.Methods Sixty-eight patients' clinical data from January 2014 to December 2016 in our hospital who underwent laparoscopic radical prostatectomy were retrospectively analyzed.35 cases with sling suspension (experimental group).Preoperative Gleason score ≤ 6,11 cases;Gleason score 7,15 cases;Gleason score ≥8,9 cases.Stage T1 1 cases,stage T2 28 cases,and T3a 6 cases.The traditional method of bladder neck group(control group) contained 33 cases.Preoperative Gleason score ≤6,9 cases;Gleason score 7,14 cases;Gleason score ≥8,10 cases.Stage T1 2 cases,stage T2 29 cases,and T3a 2 cases.The mean ages [(64.3 ± 4.3) years old and (62.6 ± 3.8) years old],BMI [(22.85 ±1.69) kg/m2 and (22.15 ± 1.32) kg/m2],prostate volume [(45.93 ± 9.08) ml and (44.12 ± 6.85) ml],preoperative PSA[(18.76 ± 5.43) ng/ml and (21.18 ± 6.55) ng/ml],preoperative Gleason of the two groups were not statistically different (both P > 0.05).All patients had no urinary incontinence.All the surgery was done by the same senior surgeon.The continence status was assessed at 1 month,2 month,3 month,and 6 month after operation.The operation time,bleeding volume,urinary leakage rate,the length of hospital stay,and positive margin between the two groups were compared.Urinary continence was assessed by daily urinary pad volume:0-1 /d for urinary continence was normal,2-3/d for mild urinary incontinence,and > 3/d for severe urinary incontinence.Results 68 cases were operated successfully.There was no conversions to open surgery.1 month,2 month,3 month and 6 month after operations,the continence rates of the experimental group were 57.1% (20/35),77.1% (27/35),85.7% (30/35),97.14% (34/35),respectively.The control group's continence rates were 36.4% (12/35),54.5% (18/35),75.8% (25/35),93.9% (31/35),respectively.At 1 month and 2 month after surgery,there was a statistically significant difference in urinary continence between the two groups (P =0.047 and P =0.040),and there was no significant difference in urinary continence between the two groups at 3 and 6 month (P =0.274 and P =0.523).There were 3 cases and 4 cases of positive margins in the experimental group and the control group,with no statistical significance (P =0.705).Conclusions Technique of preservation of bladder neck by sling suspension technique at seminal vesicle may improve the recovery of early postoperative urinary continence,and does not increase the rate of positive margin.
ABSTRACT
Objective To investigate the suppression effect of secreting-trail adenovirus on the prostate cancer PC-3 cells in the tumor bearing mice. Methods Apoptosis of PC-3 cells was measured by DAPI staining in vitro . Invasion of PC-3 cells was measured by transwell chamber assay. The tumor bearing mice were prepared and used to test the inhibition rates in different groups. The protein expression of TRAIL in different groups tumor bearing mice was determined by immunohistochemistry. The variation of cell apoptosis in different groups of tumor bearing mice was detected by TUNEL assay. Results DAPI staining showed that the apoptosis level in Ad-sTRAIL group was significantly higher than that in the control group and that in the Ad-LacZ group ,respectively. The number of PC-3 cells invading the inferior chamber in the Ad-sTRAIL group(24.8 ± 3.70) was significantly decreased compared with that in the control group(47.6 ± 4.28,q=10.68,P<0.01)and that in the Ad-LacZ group (49.6 ± 4.39,q=11.61,P<0.01). Growth inhibition assays in vivo showed the inhibition rate of Ad-sTRAIL was 3 d 8.15%,6 d 11.55%,9 d 17.23%,12 d 20.05%,15 d 27.18%,18 d 34.27%,and 21 d 33.08%,respective-ly. Immunohistochemistry results showed that the expression level of TRAIL in tumors of Ad-sTRAIL group tumor-bearing mice was significantly higher than that in the control group and that in the Ad-LacZ group. TUNEL assay showed that the apoptosis level of tumor bearing mice tumor cells in the Ad-sTRAIL group was significantly higher than that in the control group and that in the Ad-LacZ group. Conclusion The secreting-trail adenoviral vector could inhibit the growth of tumor bearing mice tumor cells,furthermore it could induce the apoptosis of PC-3 cells in the tumor bearing mice.

ABSTRACT
Female ureterovaginal fistula (UVF)is pathological communication between the ureter and the vagina,which commonly occurs as a complication of ureteral injuries during pelvic operations,especially hysterectomy.Compared with open surgery,the incidence of UVF secondary to laparoscopic surgery was higher.The main clinical symptom of UVF is persistent vaginal leakage.The ureteral injury can be diagnosed promptly and accurately by medical history,clinical symptoms and CTU.The timing of surgical treatment for UVF is still controversial.When stenting failed,early ureteral reimplantation is necessary.The laparoscopic ureteral repimlantation should be recommended because of less invasion and quick recovery.

Objective To access the practicality and safety of a new type Balloon dilatation combined with flank supine position in percutaneous nephrolithotomy.Methods Clinical data of 60 kidney stones patients were collected and retrospectively analyzed.This group of patients had been admitted and selected according to the inclusion criteria in our institute from July.2012 to Sep.2013.There was no obvious difference in sex,age,body mass index (BMI),stone location and size.According to the surgery approaches,this group of patients was divided into ballon group (dilated by balloon dilatation) and Amplatz group (dilated by Amplatz fascial dilation) and in each group there were 30 cases.All these patients received the surgery by the same group of surgeons.We collected the data of one-time success puncture rate,success puncture time,puncture complications (kidney calices fracture,perinephric fluid collection and postoperative delayed hemorrhages etc.),removing stones time and stone free rate.Results Compared with Balloon group,Amplatz group had a significant difference (P<0.05) in one-time success puncture rate [100% (30/30) vs 90% (27/30)],success puncture time [(6.1±2.3)min vs (13.3±3.6)min],puncture complications [3%(1/30) vs 13%(4/30)] and removing stones time [(11.7±2.0)min vs (21.5±3.1)min]; but no significant difference (P>0.05) in stone free rate [87% (26/30) vs 83% (25/30)].Conclusions Balloon dilatation combined with flank supine position in percutaneous nephrolithotomy is easy for surgery.It can establish the surgery access more accurately and faster,decreases removing stones time and reduces operative complications.
ABSTRACT
Objective To analyze psychological status of the donors and the recipients before and after the relative kidney transplantation.Method Symptom checklist 90 (SCL-90) were performed for 147 renal transplant recipients and donors preoperative and postoperative.Statistical analysis were performed to analyze the scores between the recipients,donors and normal standards.Results Over 90% recipients were of obvious anxiety preoperative.The scores of most factors of recipients were significantly higher than those of donors.The scores of somatization,interpersonal sensitivity,depression,anxiety,hostility,phobia and paranoia between two groups has statistical significance(P<0.05).Part of recipients retest SCL-90 3 month after operation,the data showed that the scores of somatization,interpersonal sensitivity,depression,anxiety,hostility were obviously declined after operation(P<0.05).And the test also showed that most of the donors were willing to help preoperative.Conclusion Preoperative psychological test was useful in preoperational psychological intervention for transplantation recipients.It can increase the safety of the recipients during perioperative period.
ABSTRACT
Objective To analyze the clinicopathologic characteristics and treatment of primary and secondary bladder mucosa lymphoma. Methods From June 1996 to September 2011,8 cases of bladder mucosa lymphoma patients including primary bladder mucosa lymphoma patients (2 males and 3 females)and secondary bladder mucosa lymphoma patients ( 1 male and 2 females) were treated in our institute.The patient's mean age was 68 years (ranged from 57 to 78 years),and the other 3 secondary bladder mucosa lymphoma patient's mean age was 61 years (ranged from 41 to 81 years).7 of 8 patients accepted transurethral resection of bladder tumor combined with CHOP chemotherapy and radiotherapy,and 1 patient abandoned treatment.CHOP chemotherapy and radiotherapy were performed at 2 weeks post-operatively.Secondary bladder mucosa lymphoma patients accepted 3-dimensional conformal 6000 cGy radiotherapy.Urinary CT examination showed that there were round or oval irregular tumors in the wall of urinary bladder,whose diameters were 1 to 4 cm.Tumor edges were glossy and tumor density were uniform.In addition,the bladder wall with tumor was uneven.In contrasted CT,the tumors appeared obviously enhanced.7 cases had cauliflower-like tumors found by cystoscope,and there were necrosis-calcification area in the center of tumors.1case appeared multiple tumors,which consisted of one big tumor and three smaller ones. Results There were 5 cases of primary bladder mucosa lymphoma, including 3 bladder mucosa associated lymphoma (MAL) cases and 2 diffuse large B cell lymphoma cases.There were 3 secondary bladder mucosa lymphoma cases including 2 diffuse large B cell lymphoma cases and 1 generalized follicular cystic central lymphoma case,which belongs to the tuberous sclerosis Hodgkin lymphoma.Immunohistochemical analysis showed that CD20,CD21,CD43 staining were positive in low grade MAL (3 cases).However,CD3,CD20,CD31 staining were positivein high grade MAL (5 cases). All patients were followed up 3 to 44 months.3 cases of secondary malignant lymphoma patients died after diagnosed after 3 to 13 months.5 cases of primary malignant lymphoma patients were all survived. 1 case recurred 14 months after surgery and accepted TURBT and CHOP chemotherapy again.Pathologic diagnosis showed the transformation from peripheral zone of bladder mucosa associated lymphoma to diffuse large B cell lymphoma.The patient was free of recurrence. Conclusions MAL and diffuse large B cell lymphoma are the most common type of bladder mucosa lymphoma.Primary and secondary diffuse large B cell lymphoma have similarities in histological analysis,but the former prognosis is better than the latter's. Transurethral resection of bladder tumor combined with chemotherapy and radiotherapy can prevent the relapse of MAL in short term and long term with good tolerance,and can be used as ideal treatment of MALT.
ABSTRACT
Objective To compare the clinical characters and hemodynamic data of the prone position and supine position percutaneous nephrolithotomy. Methods Patients with kidney stones in 100 cases were randomly assigned into the supine position group and prone position group.There were 50 cases in each group.The following data were recorded at preoperative,intraoperative,change position:the blood pressure,heart rate,respiration,saturation of blood oxygen and blood gas analysis results.The VAS score was recorded in patients for postural comfort,dyspnea and pain score. Results The systolic blood pressure in the preoperative,intraoperative,postoperative on supine position and prone position were as follows:(137±12),(119±15),(115±17) mm Hg and (137±10),(110±18),(104±16) mmHg.The diastalic blood pressure was as follows:( 81 ± 9 ),(74 ± 8 ),(63 ± 14 ) mm Hg and ( 84 ± 8 ),(63 ± 9 ),(60 ± 15) mm Hg.Compared with preoperative,there was a blood pressure decreased in both groups.The blood pH at preoperative,intraoperative,postoperative in supine position and prone position:7.4 ± 0,7.3 ± 0,7.3 ± 0 and 7.4 ± 0,7.3 ± 0,7.3 ± 0.The bass excess (BE) of two groups were:(2.1 ± 0.5),(-2.7 ±0.5),( -1.5 ±0.5) mmol/L and (3.2 ±0.5),(-3.8 ±0.5),(-2.5 ±0.5) mmol/L.Compared with preoperative data,the pH and BE declined in both groups.The prone position had more pronounced decrease in serum sodium,serum potassium; but with no significant difference.Supine group in postural comfort and breathing difficulties were 1.6 ± 0.4 and 7.1 4± 05,while prone group were 7.5 ± 0.2 and 1.4 ± 0.3.The supine position showed better in postural comfort and breathing difficulties with statistical significance. Conclusions Compared with the prone position,the supine positioned percutaneous nephrolithotomy could have less influence on hemodynamics,blood gas analysis.It could have better postural comfort.
ABSTRACT
Objective To investigate the safety and efficacy of percutaneous nephrolithotomy (PCNL) in a new operative position, flank suspended supine position. Methods The new position hold affected flank suspended by raising the ipsilateral shoulder and haunch with two 3-liter saline bags, and set up waist bridge simultaneously. From March 2010 to October 2010, a series of 173 patients underwent PCNL with the new supine position under epidural anesthesia. The average age was (50± 11) years, and the average bulk of the stone was (2. 9±1.0) cm. All patients were placed in the new supine position. Under ultrasound guidance, the desired calix or pelvis was punctured near the posterior axillary line, then dilating the tract and establishing the 16 F or 20 F tract for PCNL. Results The pelvicaliceal system could be successfully approached in all patients. The procedure was well tolerated in all patients. Mean operation time was (86 ± 34) min. 80. 3% of the patients were rendered free of stones by the initial PCNL. Thirty-four cases had residual stones, and a second PCNL was performed in 16 cases to clear the residual stones. Only 1 patient required blood transfusion.None of the patients suffered visceral injury. Conclusion The new supine position is safe and effective for PCNL.
ABSTRACT
Objective To compare the health related quality of life (HRQoL) of ileal conduit versus orthotopic ileal neobladder using the FACT-BL scale.Methods One hundred and thirty patients underwent radical cystectomy and urinary diversion for invasive bladder cancer from Jan 2006 to Dec 2010 at our hospital.According to different urinary diversions,patients were divided into ileal conduit (IC) and orthotopic ileal neobladder (NB).HRQoL was assessed using FACT-BL.The following scores calculated from the FACT-BL questionnaire and list:physical well-being ( PWB ),social/family well-being ( SWB ),emotional well-being(EWB),functional well-being( FWB),overall bladder-special subscale and total FACT-BL were included.A high FACT score indicated a high level of HRQoL.The medical records of each patient were then reviewed.Clinical parameters including age,sex,type of diversion and pathological status were recorded and analyzed.Results A total of 94 questionnaires were collected,of these patients 50 had an IC and 44 had an NB.Among the respondents,the age at surgery was significantly younger in NB group than IC group (P =0.014 ).While the percent of males,follow-up years and pathological stage T3 or greater revealed no significant difference.The NB group got significantly higher scores in PWB,SWB,EWB and FACT-BL than the IC group.Which indicated that the HRQoL was higher in patients following orthotopic ileal neobladder.Conclusions The HRQoL was better in patients who followed orthotopic ileal neobladder than those who followed ileal conduit.This may indicate that orthotopic ileal neobladder should be considered first when making a decision about which urinary diversion should be used.
