Background : Percutaneous Nephrolithotomy (PCNL) is the treatment of choice in removal of renal and proximal ureteral calculi. The primary goal of PCNL is to achieve stone free status while minimizing morbidity and complications. In recent years, the instruments used have been miniaturized in an effort to decrease morbidity associated with standard PCNL as well as increase the efficacy of stone removal. The aim of this study is to compare the safety and efficacy of PCNL using different tract size. Materials and methods: This hospital based prospective interventional study was conducted on patients with 1 to 4 cm renal stones who underwent PCNL either by Minior Standard PCNL technique in Chattogram Medical College Hospital and different private hospitals in Chittagong from July 2016 to June 2018. Patients aged above 12 years of age, irrespective of gender with normal renal function were evaluated to compare stone clearance, total operative time, need for blood transfusion, postoperative pain and other complications. Those who had previous history of open renal surgery, active urinary tract infection, renal malformation, uncorrected coagulopathy and morbid obesity were excluded. Results: A total of 64 patients were enrolled consecutively for PCNL who were divided equally into two groups randomly for minimally invasive PCNL (Mini- PCNL) and Standard PCNL. The average stone size in mini-PCNL group was 2.64 ± 0.94 cm and 2.776 ± 0.97 cm in standard-PCNL group. Mean tract size was 18.44 ± 1.32 F (16-20) and 26.7 ± 5 F (24-30) respectively. In mini-PCNL operative time was significantly longer than that of standard PCNL with 110.31 ± 21.77 vs 95.94 ± 19.82 min respectively. Conversely, there was an advantage of mini-PCNL over the standard one in terms of a significantly reduced hemoglobin drop (0.5 ± 0.25 vs. 0.8 ± 0.34) gram and hospital stay (2.13 ± 0.79 vs.3.38 ± 1.13 days) respectively though there was no statistical difference in terms of stone clearance rates between two groups (86.7% vs. 93.33%). There was no statistical difference in terms of Visual Analogue Scale (VAS) score (5.44 ± 1.5 vs.6.19 ± 1.65) for pain perception. The complication rate of mini-PCNL had no significant difference with that of standard PCNL (10% vs 13.6%). No statistical difference was recorded in terms of postoperative fever (³38oC) between two groups (2 in each group, 6.67%, p=1). Blood transfusion requirement was much less in mini PCNL group (10% vs. 33.33%). Conclusion: In addition to minimal bleeding and excellent stone clearance, mini- PCNL has several features for which it should be considered as an alternative or adjunct to standard PCNL, URS and ESWL. These include safe supra-costal puncture, excellent access to nearly all calyces and upper ureter, less hospital stay and suitable for large stones also. Future studies should continue to refine methods to assess complexity and safety and to determine consensus on the use of mini- PCNL. Chatt Maa Shi Hosp Med Coll J; Vol.18 (2); July 2019; Page 18-22

Renal stones are the third most common problem affecting about 10% of global population. The management of nephrolithiasis has undergone a complete transformation since the 1980s. Percutaneous nephrolithotomy (PCNL) has established itself an effective and safe technique that delivers high stone-free rate as well as overall shorter treatment time. We aim to compare the outcome of mini-PCNL with standard-PCNL in patients presenting with renal stones. In all, 90 patients fulfilled the selection criteria and randomized into two groups. Group A underwent mini-PCNL whereas Group B underwent standard-PCNL. Pre-operative hemoglobin level was recorded. Duration of procedure as well as drop in hemoglobin level was also recorded. A kidney, ureter, and bladder (KUB) X-ray was performed to confirm the presence of of stone and stone-free status. The mean age of patients in mini-PCNL group was 43.11 years and in standard-PCNL group, it was 36.91 years. The mean stone size in patients of mini-PCNL group was 29.53 mm and 31.58 mm in standard-PCNL group. The mean duration of renal stone in mini-PCNL group was 1.91 years and that in standard-PCNL group 1.80 years. The mean operative time in mini-PCNL group was 59.56 min and 61.22 min in standard-PCNL group. The mean fall in hemoglobin in mini-PCNL group was 0.38 g/dL and that in standard-PCNL group 0.51 g/dL. In mini-PCNL group, stone clearance was observed in 42 (93.3%) patients, while in standard-PCNL group, it was observed in 45 (100%) patients. This difference was insignificant (P > 0.05). Mini-PCNL and standard-PCNL have no significant differences in terms of outcome, operative time, and stone clearance, although fall in hemoglobin level was less in mini-PCNL group, which showed less blood loss in this group, thereby making it a more appropriate method for renal stone removal.

Introductions: Renal stone disease is one of the common urological disorders with prevalence approximately 2-3% in the general population and the incidence in children is increasing at a rate of 4% per year. Miniaturization of endoscopic instruments, minimally invasive endoscopic procedures of mini percutaneous nephrolithotomy (miniPCNL) in children is increasingly used. This study was conducted to assess the outcome of miniPCNL in pediatric population. Methods: This retrospective study analyzed the outcome of miniPCNL in children below 18 years of age from August 2015 to July 2018 at Patan Hospital, Nepal. Ethical approval was obtained. Outcome was assessed descriptively on stone localization, puncture success, stone clearance, bleeding requiring transfusion, gross hematuria, urosepsis, operative time, hospital stay, mortality and need of second procedures. Results: A total of 26 patients underwent miniPCNL, mean age 10.8±5.45 years (1-18 years), mean operative time was 122±26.03 minutes and mean hospital stay was 3.2±1.12 days.  Postoperative transfusion was required in 1 (2.6%), gross hematuria occurred in 1 (2.6%), no urosepsis, no conversion to open surgery. Complete stone clearance was achieved in 22 (84.61%) patients.  Mortality was nil. Second procedure was required in 4 (15.38%) to achieve residual stone clearance. Conclusions: Our study shows miniPCNL is an effective and safe procedure with minimal morbidity for the treatment of pediatric renal stones.

The aim of this paper is to assess the efficiency and safety of the tranexamic acid in reducing blood loss and the need for transfusion in patients diagnosed with staghorn calculi treated by percutaneous nephrolithotomy. Percutaneous nephrolithotomy (PCNL) is a minimally invasive technique used for large kidney stones. Hemorrhagic complications and urinary sepsis are serious complications associated with this type of surgery. Tranexamic acid is an antifibrinolytic drug that has the property of reducing intra or postoperative bleeding. The experience with tranexamic acid in preventing blood loss during percutaneous nephrolithotomy for is limited. The use tranexamic acid in percutaneous nephrolithotomy for staghorn type stones is safe and is associated with reduced blood loss and a lower transfusion rate.

The aim of this study is to assess the efficiency and safety of the tranexamic acid in reducing hemmorrhagic complications and transfusion requirements in patients with renal lithiasis treated by percutaneous approach. Percutaneous nephrolithotomy (PCNL) is a minimally invasive technique used for large kidney stones (]20mm). Urinary sepsis and intra or postoperative bleeding are the very serious complications associated with this type of procedure. Tranexamic acid is used in the treatment of many haemorrhagic conditions. The experience with tranexamic acid in preventing bloodloss during percutaneous nephrolithotomy is very limited. The use tranexamic acid in percutaneous nephrolithotomy is safe and is associated with reduced blood loss and a lower transfusion rate.

Background We aimed to compare the efficacy and safety of laparoscopic pyelolithotomy (LPL) versus percutaneous nephrolithotomy (PCNL) for treating renal stones larger than 2 cm. Methods We searched the PubMed, Embase, Web of Science, SinoMed, and Chinese National Knowledge Infrastructure databases for studies that compared the surgical outcomes of LPL and PCNL. We conducted a meta-analysis of the retrieved studies, expressed as weighted mean difference or risk ratios with 95% confidence intervals. Results We included 25 studies (1831 patients). LPL was associated with a significantly higher stone-free rate, lower rates of blood loss, complementary treatment, blood transfusion, and complications, and less reduction in hemoglobin level compared with PCNL. LPL and PCNL were similar in terms of duration of hospital stay, conversion rate, changes in glomerular filtration rate and creatinine level, and mean time of postoperative analgesia. However, LPL was associated with a longer operation time than PCNL. Conclusion LPL appears to be more effective and safer than PCNL in patients with large renal stones, by increasing the stone-free rate and reducing blood loss, complementary treatment, blood transfusion, and complications compared with PCNL. LPL may thus be a useful modality for treating patients with large renal stones.

Background: RIRS has become an important treatment option for kidney stones in pediatric patients with the development of new-generation ureteroscopy and holmium laser. The present study was conducted to assess cases of retrograde intrarenal surgery. Subjects and Methods: The present study was conducted in a tertiary care centre over a period of one year on 120 cases of retrograde intra renal surgery (RIRS) performed in both genders. Renal stone location and stone clearance, laterality, stone size, operative time, hematuria, postoperative pain & fever, urosepsis, hospital stay, residual stones and need of an adjunctive procedure to achieve residual stone clearance. Results: Out of 120 patients, males were 70 and females were 50. Stones were detected in upper calyx in 50 cases, middle calyx in 40, lower calyx in 20 and pelvis in 10 cases. The mean size of stones was 8.1 mm, operative time was 62.1 minutes, hospital stay was 3.6 days, clinically insignificant radiological fragments were seen in 35 cases and residual stones were seen in 20 cases. Maximum cases of CIRF were seen in middle calyx (15) and residual stones were seen in lower calyx (7). The difference was significant (P< 0.05). Common complications were fever in 7, hematuria in 3, flank pain in 4 and urosepsis in 2 cases. Conclusion: Authors found that retrograde intrarenal surgery is a technically safe and effective procedure for the treatment of renal stones.

Objective: Aim of the present study was to evaluate the safety and efficacy of Percutaneous Nephrolithotomy (PCNL) in the Galdakao- Modified Supine Valdivia (GMSV) position in order to predict operative time, stone-free rate and onset of complications taking into account comorbidity, stone-related parameters and anatomic upper urinary tract abnormalities. Material and methods: A prospective evaluation of patients who underwent to PCNL in GMSV position for renal stones &gt; 2 cm, from January 2009 to February 2015 was performed. According to the technique, upper urinary tract abnormalities, stone chemical and morphological characteristics, and patients' history were matched with operative outcome, in terms of stone-free, intervention time and incidence of perioperative complications. Results: Seventy-two cases were collected; mean operative time was 105 minutes (DS 41): staghorn stones and the presence of comorbidity resulted statistically significant variables. The complication-rate resulted in line with data showed in literature: hyperpyrexia and hemorrhage were the more frequently complications found. The overall stone-free was reached in 48 patients (67%), and it was influenced by patients’ anatomic abnormalities. Conclusions: In the treatment of renal stones, PCNL may be a safe and effective choice; nevertheless, patients’ anatomic abnormalities or staghorn-stones may influence the outcomes. Thus, a prospective study with a larger population is needed to verify our outcomes.

Abstract Background: Percutaneous nephrolithotomy (PCNL) is a primary treatment method for renal stones, but infection is a very common postoperative complication. Systemic inflammatory response syndrome (SIRS) is a stage of the infection process and a very important early clinical manifestation of sepsis, so identifying the risk factors associated with SIRS after PCNL is important for ensuring patient safety and preventing sepsis.Objective: To analyze the risk factors for SIRS after PCNL, identify the predictive factors, and perform risk factor analysis.Methodology: Between September 2016 and September 2017, 352 patients who were diagnosed with renal stones and treated with PCNL were included in this study. The patients were divided into two groups according to whether SIRS occurred. Univariate analysis was performed on the related risk factors, including patient age; gender; body mass index; urine culture; number, types and quantity of rental stones; diabetes; blood glucose; complications; hospital stay; residual stones; and Guy’s degree. Then, logistic regression was used to perform multivariate analysis and establish a predictive model.Results: A total of 352 patients with renal stones were treated with PCNL, and 106 patients (30.1%) developed SIRS after surgery. Operative time, preoperative fever and diabetes were found to be risk factors, and the logistic regression results indicated that diabetes (OR=2.049, 95%CI 1.008~4.166) and operative time (OR=1.011, 95%CI 1.003~1.019) could be entered into the regression equation. Therefore, the predictive regression model was P=1/[1+e-(-2.097+0.712 diabetes + 0.012 operative time)].Conclusion: Diabetes and operative time are independent risk factors for SIRS after PCNL, so the probability of SIRS after PCNL can be determined according to these two indicators.
