Introduction: We describe laparoscopic ureterolithotomy with renal stone extraction using a stone basket under flexible ureteroscopy. We describe its efficacy through a laparoscopic port and a ureterotomy site in patients with large upper ureteral stone and small renal stones.Methods: Between January 2009 and February 2012, we performed laparoscopic ureterolithotomy with renal stone extraction using a stone basket under flexible ureteroscopy in 11 patients who had upper ureteral and renal stones. The retroperitoneal approaches were used in all patients using 3-4 trocars.Results: All procedures were performed successfully without significant complications. Mean operative time was 78.5 minutes (range: 52-114 minutes). The mean size of ureteral stone was 19.91 mm (range: 15-25 mm). In addition, 25 renal stones (mean size 7.48 mm, range: 2-12 mm) were removed from 11 patients. The mean length of hospital stay was 3.5 days (range: 2-6 days).Conclusions: Laparoscopic ureterolithotomy with renal stone extraction using a stone basket under flexible ureteroscopy can be considered one of treatment modalities for patients with large upper ureteral stones accompanied by renal stones who are indicated in laparoscopic ureterolithotomy.

Abstract Background The goal for using smaller caliber instruments in PNL was to reduce the access-related complications and to decrease morbidity. The objective of this study was to evaluate the safety and efficacy of Chinese minimally invasive percutaneous nephrolithotomy (MIPNL) in the treatment of renal stones ≤ 20 mm. Results Sixty-seven patients completed the study protocol. The mean age was 41.10 ± 13.99 years (range 18–68 years). There were 43 (64%) male and 24 (36%) females. The mean stone size was ranged from 78.5 to 439.6 mm2 (mean ± SD 172.48 ± 69.54 mm2). The overall SFR was (82%). Twelve (18%) needed post-MIPNL auxiliary procedure, in the form of second MIPNL in 3 (4.5%) cases, SWL in 7 (10%), and RIRS in 2 (3%) cases. The intraoperative complication was present in four patients (5%) include bleeding necessitate blood transfusion in one patient (1.5%) and renal collecting system perforation 3 (4.5%). The postoperative complication was urine leakage 5 (7.5) and fever in 6 (9%) of patients. Conclusion Chinese MIPNL is safe and effective method for treatment of renal stone ≤ 20 mm size with satisfactory SFR and low complication rate when SWL failed or contraindicated. It is considered a feasible treatment alternative to standard PNL, in the absence of flexible URS or miniature nephroscope.

Introduction: Urinary stones are one of the most common and painful diseases of humans after urinary tract infections and prostate diseases. Objectives: The aim of this study was comparing the efficacy and complications of combined cystone and hydrochlorothiazide with cystone monotherapy in the treatment of upper urinary stones. Patients and Methods: In this randomized clinical trial 80 patients older than 15 years old with renal and ureteral stones less than 10 mm after taking informed consent form were allocated randomly in one of two groups. Patients with azotemia, hydronephrosis, bothersome pain and pregnant women were excluded. In the first group, combinations of cystone and hydrochlorothiazide tablets (every 12 hours, two 100 mg cystone and 25 mg hydrochlorothiazide) were prescribed. In the second group, cystone were prescribed as the first group. One month later, patients were followed by kidney, ureter, and bladder x-ray (KUB) and ultrasonography and the success of treatment was determined by changing the size of stones and report of stone passage by the patients. All data were collected and analyzed by SPSS software version 23 and statistical tests. Results: The mean age of the patients in combined and single groups were 48.02±13.72 and 44.15 ± 14.86(P = 0.24) years respectively. The mean size of stone after treatment in two groups was 1.72±0.98 and 1.85±0.78 mm respectively (P=0.53). Regarding efficacy of combined and single group, more than 90% of the patients reported stones passage after the intervention (P=0.06). There were no significant differences in mean blood urea (P=0.38) and serum creatinine (P=0.53) after treatment in two groups. Conclusion: The results of this study showed that combination of cystone and hydrochlorothiazide do not increase the efficacy of cystone in treatment and passage of urinary stones, although in both groups stone passage significantly increased.

Abstract Objectives The aim of this study was to assess the feasibility, performance, and complications of a non-surgical, minimally-invasive procedure of deep contraceptive implant removal under continuous ultrasound guidance. Methods The ultrasound-guided procedure consisted of local anesthesia using lidocaine chlorhydrate 1% (10 mg/mL) with a 21-G needle, followed by hydrodissection using NaCl 0.9% (9 mg/mL) and implant extraction using a Hartmann grasping microforceps. The parameters studied were the implant localization, success and complication rates, pain throughout the intervention, volumes of lidocaïne and NaCl used, duration of the procedure, and size of the incision. Between November 2019 and January 2021, 45 patients were referred to the musculoskeletal radiology department for ultrasound-guided removal of a deep contraceptive implant and were all retrospectively included. Results All implants were successfully removed en bloc (100%). The mean incision size was 2.7 ± 0.5 mm. The mean duration of the extraction procedure was 7.7 ± 6.3 min. There were no major complications (infection, nerve, or vessel damage). As a minor complication, 21 patients (46.7%) reported a benign superficial skin ecchymosis at the puncture site, spontaneously regressing in less than 1 week. The procedure was very well-tolerated, with low pain rating throughout (1.0 ± 1.5/10 during implant extraction). Conclusions Minimally invasive removal of deep contraceptive implants under continuous ultrasound guidance alone is feasible, effective, and safe. In the present cohort, all implants were successfully removed, whatever the location, with short procedural time, small incision size, low pain levels, and no significant complications. This procedure could become a gold standard in this indication. Key Points • Minimally invasive removal of deep contraceptive implants under continuous ultrasound guidance alone is feasible, which led to a success rate of 100% whatever the location (even close to neurovascular structures), with only a small skin incision (2.7 ± 0.5 mm). • The procedure was safe, quick, without any major complications, and very well tolerated in terms of pain. • This minimally invasive ultrasound-guided procedure could become the future gold standard for the removal of deep contraceptive implants, as an alternative to surgical extraction, even for implants in difficult locations such as subfascial ones or those close to neurovascular structures.

Background: Renal stone disease is a common disorder with a prevalence ranging from 4-15% in different parts of the world. Modalities of kidney stone management includes drug therapy, extracorporeal shock wave lithotripsy (ESWL), percutaneous nephrolithotomy (PCNL), Retrograde intrarenal surgery ureteroscopy (RIRS) and open surgery. ESWL is an acceptable technique and widely used because it is a non-invasive treatment and does not require anesthesia and usually done on an outpatient basis. Generally, ESWL is the treatment of choice for kidney stones <1 cm. However, not all ESWL treatments are successful. The success rate has been reported to be between 50%-87%, depending on various factors. This study was conducted in order to evaluate thefactors affecting renal stones treatment by extracorporeal shock wave lithotripsy (ESWL).On the basis of different variables andfactors affecting the renal stones treatment by ESWL was evaluated. Objectives: To evaluate the factors affecting the outcome of Extracorporeal Shock Wave Lithotripsy (ESWL) in the treatment of renal stone in adults.To assess the success and failure rate by using ESWL for treatment of renal stone, to determine the effects of stone related factors to correlate the success rate with characteristics of the patients condition of the urinary tract and stone features; to observe the patient groups most likely to benefit from or fail an initial intervention with ESWL and to evaluate the post ESWL complications. Materials and methods: This is a prospective observational and analytical, hospital based study. Total 500 patients with single or multiple radio-opaque renal stones were treated with ESWL monotherapy using Siemens MODULARIS Variostarlithotriptor. This study was carried out inthe Department of Urology, Combined Military Hospital, Dhaka for a period of two years between 01 July 2015 to 31 July 2017. The results of treatment were evaluated after 3 months of follow-up. Treatment success was defined as complete clearance of the stones or presence of clinically insignificant residual fragments (<3mm). The results of treatment were correlated with the patient characteristics (age, sex, body mass index) and stone features (size, site, number & radio density). Results: At 3-months follow-up, the overall success rate is 87.6%. Among them, repeated ESWL sessions were required in 266 patients (53.2%). Post-ESWL complications were recorded in 62 patients (12.4%). Using the chi-square test, only four factors have a significant impact on the success rate, namely stone site, size (the largest diameter of the stone), stone number, BMI (body mass index) of the patient. The success rate is highest for stones located in the upper calyx (136/136; 100%) and lowest for those located in lower calyx 104/78; 75%) (p=0.001). Stone with a largest diameter of <10mm are associated with a success rate of 93.6% (307/328), compared to 76.2% (131/172) for those with a diameter of >10mm (p=0.001). The success rate was also higher for single stone (396/437; 90.6%) than multiple stones (42/63; 66.7%) (p=.001). Patients with lower BMI (<24) have a better success than higher BMI (>25) (p=.001). Other factors including age, sex and stone radio density compared to ipsilateral 12th rib have no significant impact on the success rate. Conclusion: The success rate of ESWL for the treatment of renal stones can be predicted by stone size, location, number, and patients BMI.

Objective: To compare the clinical outcomes of ultrasound-guided percutaneous nephrolithotomy (US-PCNL) in lateral position and anatrophic nephrolithotomy (ANL) in the treatment of staghorn renal stones.Methods: This study includes individuals with staghorn renal stones who had an operation at Buri Ram Hospital in Thailand between October 2016 and July 2020. They were divided into two groups; group I includes patients undergoing US-PCNL (n= 114) and group II includes patients undergoing ANL (n=112). The outcomes regarding stone-free rates, the stone clearance rate, operative times, length of hospitalization, and complications were collected and analyzed.Results: The patient’s demographics and stone characteristics were not significantly different between the two groups, except that the ANL group had more preoperative hydronephrosis (78.6% vs. 53.5%, p < 0.001). Regarding the primary outcome, the stone-free rate was significantly lower in the US-PCNL group (47.4% vs. 75.9%, p < 0.001), whereas the stone clearance rate was not significantly different (96.4±6.0% in the US-PCNL group and 97.7±5.8% in the ANL group, p = 0.098). The major and minor complications between the two groups were not significantly different; however, the US-PCNL group had a significantly lower transfusion rate than the ANL group (3.5% vs. 17.9%, p < 0.001). The total operative time in both groups was not different; however, the length of stay at hospital for the US-PCNL was significantly shorter than for the ANL group (10.0 vs. 12.9 days, p = 0.002).Conclusion: The ANL had a higher stone-free rate; however, the stone clearance rate was not significantly different between the US-PCNL and ANL groups. There were many advantages of the US-PCNL over the ANL, such as less blood transfusion, shorter length of hospitalization, and no radiation exposure for the patients or the medical personnel, while the complications were not different between the two groups.

Nephrolithiasis accelerates the renal failure in the patients with ADPKD. In order to evaluate the role of percutaneous nephrolithotomy in management of calculus in these patients, 11 patients with autosomal dominant polycystic kidney disease and renal stones were included in the study. Two patients had bilateral renal stones. All patients were treated by percutaneous nephrolithotomy under ultrasound guidance. 13 percutaneous nephrolithotomy procedures were performed in 1 stage by the urology team under ultrasound guidance. 5 people received second operation with flexible nephroscopy in lateral position. The success rate and morbidity and mortality of the technique and hospital stay were recorded.Results. The puncture procedure was fully successful in all cases. The renal function improved in these patients. 5 patients had moderate fever after the surgery. 5 patients received flexible nephroscopy to take out the residual calculi. 2 persons had ESWL therapy after the surgery.Conclusion. PCNL is an ideal, safe, and effective method to remove the stones from those patients with no definite increase in the risk of complication. The outcome and stone-free rate are satisfactory comparable to the PCNL in the patients without ADPKD.
