Introduction: Access by ultrasonography rather than fluoroscopy in addition to reducing radiation exposure to the patient and staff, is safe and effective. Access by ultrasonography is bi-planar and real-time compared to fluoroscopy, because it provides fewer side effects and more stone free rate. Objectives: To study the complications and outcome of PCNL (percutaneous nephrolithotomy) with or without using ureteral catheter. Patients and Methods: We studied 59 patients with at least 2 cm diameter of renal stone from January to December of 2018. After general anesthesia, 35 patients in the ureteral stent group were prepared in bladder lithotomy position. Then 5-French (Fr) ureteral catheters were introduced endoscopically in stone affected side and fixed to 16 Fr urethral Foley catheters in the patients. Other 24 patients in the non-stent group following anesthesia were directed to prone position instantly. In all of the patients, ultrasonography was performed in posterior auxiliary line below the ribs in prone position. Retrograde instillation of normal saline was performed through ureteral catheter in stent-group. Then we inserted 18G Chiba needle to desired calyx without needle holder guidance in all patients. Our approach according to probe was transverse. Results: Our patients comprised of 24 men and 35 women aged 24 to 66 years. Thirteen of them had no hydronephrosis and their stone sizes ranged from 21 mm to 65 mm. Patients in the ureteral stent group were more obese compared to the non-stent group (P=0.02) in addition to significantly more operation time (P=0.03). However hydronephrosis was not significantly different between groups (P=0.3). Postoperative residual stone rate, hospital stay days and complications (Fever, blood transfusion) were the same between both groups. Only urinary leak was more common in the non-stent group (P=0.04) Conclusion: Ultra-sonographic-PCNL without inserting ureteral catheter before surgery is conceivable especially in patients with lower body mass index (BMI). Advantages and complications are same in ureteral stent and non-stent patients except urinary leak that is more common in non-stent patients.

Objective. To investigate the efficacy and safety of the oblique supine lithotomy during percutaneous nephrolithotomy (PCNL) to treat upper urinary calculi. Methods. Clinical data were retrospectively analyzed for 371 patients with upper urinary calculi who underwent PCNL at The First Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2017 to October 2020. Based on different positions, patients were divided into the observation group (oblique supine lithotomy position, 155 cases, Group 1) or control group (prone position, 216 cases, Group 2). Groups were compared for effectiveness, complications, bleeding, surgical time, clinical indicators, and hospitalization time. Results. There were no significant differences in the clinical baseline data between the two groups ( p > .05). However, the stone-free rate for patients was significantly higher in the observation than in the control group ( p < .05). Both operation time and hospital stay time were significantly lower in the observation versus the control groups ( p < .05). No significant differences were observed for complications or amount of blood loss ( p > .05). Conclusion. In patients with upper urinary calculi, percutaneous nephrolithotomy in the oblique supine lithotomy position has a higher stone-free rate than the prone position. This approach can shorten the operation and provide better comfort and quicker recovery to the patients. A further advantage is that there is no difference in safety and blood loss between the prone position and the oblique lithotomy position.

Background: The decision for using supine or prone position in percutaneous nephrolithotomy (PCNL) is still debatable. The aim of this study is to compare the efficacy and safety profile of the supine and prone position when performing PCNL. Methods: A systematic electronic search was performed using the database from MEDLINE, Cochrane library and Google Scholar from January 2009 to November 2019. The outcomes assessed were stone free rate, major complication rate, length of hospital stay and mean operation time. Results: A total of 11 articles were included in qualitative and quantitative analysis. The efficacy of PCNL in supine position as determined by stone free rate is significantly lower than in prone position (OR: 0.74; 95% CI: 0.66 – 0.83; p<0.00001), However, major complication rate is also lower in the supine group compared with the prone group (OR: 0.70; 95% CI: 0.51 – 0.96; p=0.03). There is no statistically significant difference in the length of hospital stay and mean operation time between both groups. Conclusion: Prone position leads to a higher stone free rate, but also a higher rate of major complication. Thus, the decision of using which position during PCNL should be based on the surgeon’s experience and clinical aspects of the patients.

Introductions: Fever and sepsis after percutaneous nephrolithotomy (PCNL) secondary to urinary tract infection is a major determinant of overall post PCNL complications. This study aims to analyse infective complications after PCNL in relation to pre-operative urine culture status. Methods: A comparative analysis of post PCNL infective complications in pre-operative urine culture positive (Group A) and negative (Group B) was done for one year during June 2017 to May 2018 in department of urology, Bir Hospital, National Academy of Medical Sciences, Kathmandu, Nepal. Demographics, stone characteristics, mean operative time, post-operative hospital stay and post-operative complications as per Modified Clavien classification were compared between the two groups. Results: Out of total 136 PCNL patients, 51 were in Group A and 85 in Group B. Infective complications were significantly high, 28 (54.90%) in group A compared to 20 (23.53%) in group B, p=0.004. The most common isolate was Escherichia coli 19 (37.25%), sensitive to amikacin 37 (72.55%). The mean operation time, transfusion and hospital stay was not statically different in two groups. Morality occurred in 1 (1.96%) in group A. Conclusions: Infective complications were significantly high after PCNL in patients with preoperative positive urine culture, even when it was treated to sterile with sensitive antibiotics, compared to patients with preoperative negative urine culture.

Laparoscopic Techniques

With the minimal morbidity attained using laparoscopy, its application in urologic surgery has been increasing. Using laparoscopic techniques we successfully completed the transposition and re-anastomosis of a retrocaval right ureter. Operation time was 240 minutes. The patient was allowed to walk on the first post-operative day and resumed oral intake on the second day. Administration of analgesics was not required. The ureteral stent was removed on the 24th day after operation. An intravenous urogram three months after operation showed a decrease in hydronephrosis. Laparoscopic correction of retrocaval ureter by extraperitoneal approach is a safe, feasible technique, avoiding a large surgical wound with the definite advantage of minimal disfigurement. Operating time is considerably shorter compared to the peritoneal approach as described by Baba (240’ vs 560’).

Introduction: Percutaneous nephrolithotomy has the highest stone free rate among other procedures with relatively higher complication rate. Post-operative imaging after stone surgeries has not been uniform. This study was done to study about the stone clearance by computed tomography after percutaneous nephrolithotomy. Methods: The descriptive cross-sectional study was conducted in the Department of Urology, Bir Hospital for six months duration. The patients undergoing percutaneous nephrolithotomy and those with intra-operative fluoroscopic clearance were evaluated with a low dose computed tomography after 48 hours to assess residual fragments its size and location. Patient’s demographics, stone characteristics and complications were compared between the stone free and with residual stone patients. Results: Out of 72 percutaneous nephrolithotomy performed, 40 patients were included in the study. Low dose computed tomography kidney, ureter and bladder after 48 hours of surgery detected residual fragments in 11 (27.5%) patients. The RFs size of <4mm were found in 7 (63.63%) of cases whereas RFs of >4mm were found in 4 (36.36%). The stone size was 352.47 ± 97.47 mm2 and 254.79 ± 172.68mm2 in group with residual fragments and stone free group respectively. Conclusions: Low dose computed tomography kidney, ureter and bladder done for assessment of stone clearance after 48 hours of percutaneous nephrolithomy detected residual in around one fourth of patients, however majority of them had residual fragments <4mm. Intra-operative fluoroscopic clearance may over estimate stone clearance after percutaneous nephrolithomy as about one third of patients still may have residual fragments of >4mm size.

The incidence of urolithiasis is progressively increasing worldwide, as is the surgical treatment of urinary stones. The most frequent surgery for urolithiasis is ureterorenoscopy, which is performed in the lithotomy position. This position is also used in the endoscopic approach to bladder stones. Lateral decubitus is rarely used in the treatment of urinary stones. In the case of complex kidney stones, the gold standard treatment is percutaneous nephrolithotomy. This surgery has traditionally been performed in the prone position. However, the use of the supine (Valdivia) position is increasing in recent times. Furthermore, the Galdakao-modified supine Valdivia position has been widely used for percutaneous nephrolithotomy since it was described by Ibarluzea et al. in 2007. Treatment of kidney and ureteral stones simultaneously is allowed in both supine positions. In addition, they allow the removal of encrusted stents and the easy placement of double J stents and, in the case of the Galdakao-modified supine Valdivia position, percutaneous nephrostomies. Compartment syndrome is a rare complication in the lithotomy position, but scarcely described in the supine position. This especially applies to the Galdakao-modified supine Valdivia position, in which the lower limbs are in moderate flexion, with the ipsilateral lower limb in a slightly lower position relative to the other. This complication can lead to skin necrosis, myoglobinuric renal failure, amputation, permanent neuromuscular dysfunction, and even death. Risk factors include Body Mass Index, male gender, obesity, increased muscle mass, peripheral vascular disease (advanced age, hypertension, hyperlipidemia and diabetes mellitus), height, lack of operative experience, significant bleeding during surgery, hypothermia, acidemia, combination general-spinal anesthesia, prolonged surgical time, systemic hypotension, ASA (American Society of Anesthesiologists) class or vasoconstrictor drugs. Therefore, compartment syndrome of the leg is a potentially devastating complication that must be suspected and treated through early decompression of the compartment by four compartment fasciotomy. Preventive measures reduce the incidence of this condition.
