Objective To investigate the efficacy and safety of transrectal ultrasound guided transurethral balloon dilation of the prostate (TUDP) for the treatment of benign prostatic hyperplasia (BPH).Methods A total of 23 men with BPH who had undergone TUDP were retrospectively analyzed,including 16 men with indwelling urinary catheters before the operation.During the TUDP,the prostatic apex and membranous urethra were dilated by inner balloon,and the prostatic urethra and bladder neck were dilated by outer balloon.The patients were followed up at the 1st,3rd,6th and 12th month after the operation,and the observation parameters included subjective symptoms,such as international prostatic symptom score (IPSS) and quality of life (QOL) score,and objective parameters,such as maximum flow rate (Qmax) and post-void residual (PVR).Results The operation time was 30-165 min,and the intraoperative hemorrhage volume was 5-50 ml.The IPSS scores at 1st,3rd,6th and 12th month after the operation were 10.4± 4.2,8.7±3.2,9.5±4.6 and 8.3±1.5 respectively,which were significantly decreased in comparison to the IPSS score (22.0±7.2) before the operation (P＜0.05).The QOL scores at 1st,3rd,6th and 12th month after the operation were 2.1±1.1,1.6±1.0,1.8±1.1 and 1.6±1.0 respectively,which were significantly improved in comparison to the QOL score (4.9±0.9) before the operation (P＜0.05).The Qmax at 1st,3rd,6th and 12th month after the operation were (10.5±3.4),(12.4±4.2),(10.9±3.9) and (12.7±4.6) ml/s respectively,which were significantly increased in comparison to the Qmax(1.9± 1.9 ml/s) before the operation (P＜0.05).There were 5,4,2 cases of urinary incontinence at the 1st,2nd and 3rd month after the operation,but they recovered at the 4th month follow-up.Besides,there were 3 cases suffered from epididymitis.Conclusion Transrectal ultrasound guided TUDP is a safe,effective and cheap option for the treatment of BPH,especially for the primary hospitals.

Objective: To evaluate the clinical efficacy of percutaneous nephrolithotomy combined with flexible ureteroscopy and holmium laser lithotripsy in the treatment of complicated renal calculi. Methods: Clinical data of 139 patients with complicated renal calculi from March 2013 to March 2019 in Miyun Teaching Hospital, Capital Medical University were retrospectively analyzed. There were 76 males and 63 females, the average was (47.9±3.1) years, aged from 27 to 75 years. The total patients were divided into control group (n=69) and treatment group (n=70) according to different treatment method. The patients in the control group treated with percutaneous nephrolithotorny, the patients in the treatment group were treated with flexible ureteroscopy and holmium laser lithotripsy on the bassis of the control group. Compared the operation time, hospital stays, intraoperative blood loss, effective rate and complication incidence rate between two groups. Measurement data were expressed as mean± standard deviation (Mean±SD), and t-test was used for comparison between groups; count data was compared by Chi-square test. Results: In the control group, the operation time, length of hospital stay and intraoperative blood loss were (65.85±3.83) min and (8.83±4.00) d, (130.72±1.20) ml, respectively, the treatment group were (43.44±3.16) min, (5.72±1.07) d, (96.21±0.98) ml, respectively, the difference between group there was statistical significance (P<0.05); the total effective rate of the control group was 84.0% (58/69), which was significantly lower than that of the treatment group [95.7% (67/70)], and the difference between the groups was statistically significant (P<0.05). The incidence of postoperative complications of the treatment group[2.8% (2/70)] was significantly lower than the control group[14.5% (10/69)], and the difference between the two groups was statistically significant (P<0.05). Conclusion The complicated renal calculi by percutaneous nephrolithotomy combined with flexible ureteroscopy and holmium laser lithotripsy has the advantage of short operation time, less blood loss, faster recovery and low complication incidence rates, has clinical use and promotion value.

Objective To investigate the related factors of systemic inflammatory response syndrome after percutaneous nephrolithotomy in the treatment of upper urinary tract stones.Methods The clinical data of 101 patients after percutaneous nephrolithotomy from August 2016 to April 2018 in Miyun Teaching Hospital,Capital Medical University were retrospectively analysed.Screened the independent variable such as gender,with fever or not,with diabetes or not,with hydronephrosis or not,urine leucocyte count,volume of urinary calculi,CT attenuation value of urinary calculi and presence of intraoperative infection,and analyzed the relationship those with systemic inflammatory response syndrome after surgery.Univariate and multivariate logistic regression analysis the factors related to systemic inflammatory response in patients after surgery.Results Of the 101 patients,62 cases was male,and 39 cases was female,12 (11.9％) suffered postoperative systemic inflammatory response syndrome.Univariate regression analysis indicated that the risk factors of systemic inflammatory response syndrome after percutaneous nephrolithotomy were gender,with diabetes or not,urine leucocyte count,volume of urinary calculi and presence of intraoperative infection.Furthermore,multivariate logistic regression analysis revealed that with diabetes,intraoperative infection,urine leucocyte count and volume of urinary calculi were the independent factors of systemic inflammatory response syndrome after percutaneous nephrolithotomy.Conclusion Patients with diabetes,intraoperative infection,urine leucocyte count and volume of urinary calculi could be predicted as the independent factors of systemic inflammatory response syndrome after percutaneous nephrolithotomy,but it has no relationship with gender,with a history of fever or not,with hydronephrosis or not,and CT attenuation value of urinary calculi.

【Objective】 To investigate the safety and efficacy of domestic Kangduo endoscopic robotic surgical system (SR1500) in laparoscopic partial nephrectomy via abdominal approach. 【Methods】 Perioperative data of 5 patients with renal tumors undergoing transabdominal partial nephrectomy with SR1500 at Miyun Hospital during Jul.and Aug.2023 were prospectively collected.The surgical procedure, operation time, pathological margins, intraoperative bleeding, hospital stay, and catheter removal time were recorded. 【Results】 The average tumor diameter was 1.92 cm, staged as T1a in TNM classification, with an average R.E.N.A.L score of 5.80.The mean docking time of equipment was 3.00 min, robotic arm operating time 97.20 min, and renal warm ischemia time 19.80 min.Postoperative pathology revealed negative surgical margins in all patients.No high-grade perioperative complications or device-related adverse events occurred. 【Conclusion】 Laparoscopic partial nephrectomy using the Kangduo endoscopic robotic surgical system (SR1500) via abdominal approach is safe and effective in the treatment of T1a renal tumors.
