Objective: Outcome of 45 retroperitoneal single incision laparoscopic nephrectomy of benigns nonfunction kidneys at Hue Central Hospital. Patients and method: A prospective study was perform on 45 patients with benign nonfuncion kidney, treated by retroperitoneal single incision laparoscopic nephrectomy at Department of General Surgery - Hue Central Hospital from May 2015 to August 2018. Results: Success: 42/45 patients. Mean operating time 87.5mins (50 - 155 mins), postoperative hospital stay 5-7 days. SILS Port of Covidien was inserted by 2.5 cm skin transverse incision, standard straight laparoscopic instruments were used instead of roticular instruments. Conclusion: This is a mini-invasive technical, safety and cosmetic Keywords: retroperitoneal single incision laparoscopic nephrectomy, single port nephrectomy.

Purpose: To evaluate quality of life and related factors in patients with ureteral stents. Materials and Methods: The clinical description study was performed on 83 patients with ureteral DJ stent placement follow-up of 1 month at the Department of Urology, Hue University of Medicine and Pharmacy Hospital from June, 2019 to April, 2020. Results: Average age: 49.55 ± 12.19 years. Female/male 1.13. Stone-free rate: 49.4%. Average point of the quality of life: 0.833 ± 0.137. The factors related to quality of life of patients with JJ stent: age, sex, types of operations. Conclusion: the majority of the patients with ureteral double j stent were well tolerated, pain and irritative voiding symptoms have a significant impact on health related quality of life Key words: JJ stent, quality of life, EQ-5D-5L, USSQ

Purpose: To ascertain the safety and efficacy of Semi-rigid Ureteroscopy for treating renal stones. Materials and Methods: This is a prospective descriptive study for 69 cases with renal stones have been treated by Semirigid Ureteroscopy from January 2016 to June 2020 at Hue University of Medicine and Pharmacy Hospital. Results: Out of a total of 69 patients, 58.0% (n=40) were males and 42.0% (n=29) were females. The age ranged from 25 - 75 years, with the mean age of 48.5 years. The average stone size was 20.3 mm (9 - 30 mm). Treatment were completely successful in 66/69 cases (95.7%). Surgery failure includes 3 cases (4.3%): inability to reach the renal stone in 2 case (2.9%), stone retropulsion in 1 case (1.4%). A average operative time was 48.2 minutes (20 - 75 minutes). All of cases (100%) was put the residual stent into the ureter. The mean post-operation hospital stay was 4.1 days (1 - 8 days). About early post‑operative complications, there were 11/66 cases (16.7%), include: 4 cases (6.1%) of hematuria; 5 cases (7.6%) of fever; 2 cases (3.0%) of urinary tract infection. The stone-free rate (assessed with X-ray) following S-URS was 72.7% after 1 month. We found significant differences between the size of the stone and early stone-free rates with p < 0.05. Conclusions: Semi-rigid Ureteroscopy is a safe and effective method of managing renal stones with low rate of intra‑ and early post‑operative complications. Success depends on the experience of surgeons and judicious selection of cases. Key words: Semi-rigid Ureteroscopy, renal stones, treatment

Objectives: Evaluating the morphology of the upper urinary tract of renal living-related donors with 64 Multi - Detectors Computed Tomography (MDCT). Subjects and methods: From 01/2017 to 10/2018, when carrying out a prospective study at Cardiovascular Centre of Hue Central hospital, we have performed 64 MDCT of the upper urinary tract (MDCT-UUT) on 312 renal living-related donors among which, there are 265 males and 47 females aged from 20 to 60. Results: 100% of donors experience no contrast-induced artifacts in renal parenchyme. 71.47% of visualization of contrast media (CM) of entire upper urinary tract filling and 100% of visualization of CM of top half upper urinary tract filling in both of kidney. The majority of donors have single collecting system (99.04% in right kidney and 99.68% in left kidney). The rest has partial or complete duplex collecting system. 64 MDCT has high value in detecting stone of the upper urinary tract (8.01%) in comparison with KUB Radiograph (0%) and abdominal Ultrasonography (0.32%). 100% of donors have normal renal function in the excretory phase at 5 minute after CM and NaCL 0.9% injection bolus. This allows reducing examination time and radiation exposure with the highest effective dose 5.88mSv in unenhanced and excretory phases. Conclusions: 64 MDCT-UUT contributes into more accurate diagnosis of the morphology of the upper urinary tract of renal living-related donors, helps surgeons make appropriate planning in the operation of chosen kidneys of living-related donors and transplanting into patients. Key words: Upper urinary tract - 64 MDCT - MDCT-UUT
