Purpose. To compare balloon with Amplatz for tract dilation in totally ultrasonographically guided PCNL (UPCN). Methods. We randomized 66 patients candidate for sonographically guided PCNL in the flank position in two study groups. In the first group, we used single step Amplatz dilation (AG) technique in which the 28- or 30-French Amplatz dilator is used for tract dilation. In the other group, we dilated the tract using balloon dilator (BG). We compared procedure time, success rate of dilation, and postoperative clinical outcomes and cost between two groups. Results. The rate of short dilation was higher in the Amplatz group (57.6%) compared with Balloon group (36.4%) (P=0.08). When using Amplatz for lower pole access, short dilation occurred in 81% of cases compared with 44% in the BG (P=0.02). Overall operation was longer in the AG (80±21 versus 65±20 minutes P=0.02). Stone free rate was 87.9% in the AG compared with 72.7% in the BG (p=0.12). Mean cost of the surgery was 603±85 USD and 718±78 USD in the AG and BG, respectively (P=0.0001). Hemoglobin drop, transfusion rate, renal function alteration, duration of hospitalization, and complication rate based on Clavien classification were similar in both groups. Conclusions. AG showed a higher rate of short dilation compared with BG; consequently, overall operating time was significantly longer in the AG whereas BG was significantly more expensive than AG. Bleeding and other complications were similar in two groups. We observed an advantage for balloon dilation over Amplatz when approaching the lower pole calyxes.

Objectives: To evaluate the safety and efficacy of transperitoneal laparoscopic pyelolithotomy in renal stone cases with previous renal surgeries. Patients and methods: In this prospective study, 190 consecutive patients with renal stones, who were candidates for transperitoneal laparoscopic pyelolithotomy, were enrolled. The patients were divided into two groups. In group A, 163 patients without a history of renal surgery underwent standard laparoscopic pyelolithotomy, whereas in group B laparoscopic pyelolithotomy was performed in 27 patients with a history of kidney stone surgery including percutaneous nephrolithotomy or open stone surgery. All intraoperative data including the operating time and complications such as bleeding requiring transfusion were recorded. Postoperative data such as length of hospitalization, hemoglobin level alteration, and other complications were also recorded. Results: There was no significant difference in the preoperative data such as stone size, stone site, age, sex, and stone side between the two groups. There was no significant difference in the stone-free rate between the two groups (p = 0.4). There was no significant difference between the two study groups regarding the operating time, hospital stay, stone-free rate, complications, and transfusion rate. Conclusion: Laparoscopic pyelolithotomy can be used as a safe and feasible treatment modality in the setting of previous renal surgery. The complications and stone-free rate of laparoscopic pyelolithotomy in patients with history of renal surgery are acceptable.

ObjectiveTo compare the safety and efficacy of balloon and Amplatz for tract dilation in fluoroscopically guided percutaneous nephrolithotomy (PCNL).MethodEMBASE, PUBMED, MEDLINE and the Cochrane Central Register of Controlled Trials were searched for pertinent studies up until 30 October 2019. Pooled effects were calculated as ORs with 95% CIs or mean differences (MD) with 95% CIs. Endpoints included postoperative decrease in haemoglobin, transfusion rate, complication rate, successful dilation rate, stone-free rate, fluoroscopy time, access time, total operation time and length of postoperative hospitalisation (LPH). Bonferroni’s correction was intercalated to reduce the likelihood of making a meta-analytical false positive.ResultsOne randomised controlled trial and five controlled clinical trials were included, which involved 1317 patients in total. We found a lower drop in postoperative haemoglobin for patients receiving balloon dilation compared with those in the Amplatz group (MD=−0.21, 95% CI −0.33 to 0.09, p=0.0005; Bonferroni correction a=0.005). Access time in the balloon group was also, on average, 2.61 min shorter than the Amplatz group (MD=−2.61, 95% CI −4.20 to 1.01, p=0.001; Bonferroni correction a=0.005). No significant differences were identified between the two dilation methods in terms of transfusion rate, complication rate, successful dilation rate, stone-free rate, fluoroscopy time, total operation time and LPH.ConclusionBalloon dilation is a safe and effective tract dilation technique for access creation during fluoroscopically guided PCNL. Both of methods have similar success rates although balloon dilation is associated with significantly less postoperative haemoglobin decline and shorter access time. Therefore, balloon dilation appears to be the superior tract dilation technique, but further confirmatory research is required to confirm these findings.

Objective: To evaluate the feasibility, safety and efficacy of one-shot dilation (OSD) in standard percutaneous nephrolithotomy (PCNL). Methods: This is a prospective, single -center study conducted between January 2017 to June 2019. Patients who underwent PCNL using one shot dilatation (21 – 24 Fr) for access in PCNL were included in the study. Access time, fluoroscopy time, successful dilation time, stone free rate, decrease hemoglobin level and transfusion rate, complication rate, length of post operative hospital stay, cost were recorded. Data was analyzed and reported using summary statistics. Results: A total of 30 patients were enrolled in this survey. 30 patients in one shot dilation (OSD) group.The mean age was 39.5 years. Control group of 30 patients were included in standard PCNL procedure where method of tract dilation was done by regid Amplatz dilators. Access time and fluoroscopy time in OSD group was approximately shorter. Statistically it was significant. Successful dilation and stone free rate were subsequently 98% and was significant. Data collected included patient access time, radiation exposure, total operating time, preoperative and postoperative hemoglobin concentrations, tract dilatation failures, complications and transfusions. Conclusion: The use of one shot and standard prone position under general anaesthesia combines the advantages of these both methods including less radiation exposure and shorter access and operative time. One shot dilation technique is safe, economical and feasible technique with added advantage,lesser radiation exposure and lesser chance of blood transfusion.

ObjectiveThe purpose of this study was to systematically review the outcomes of the use of one-shot dilation (OSD) and serial tract dilation for percutaneous nephrolithotomy (PCNL).MethodsA systematic review and meta-analysis was conducted. The randomised controlled trials (RCTs) included in the study were identified from EMBASE, MEDLINE and the Cochrane Central Register of Controlled Trials. The last search was performed on 30 April 2018. Summary effects were calculated as risk ratios (RRs) with 95% CIs or mean differences (MDs) with 95% CIs. The endpoints included access time, fluoroscopy time, successful dilation rate, stone-free rate, postoperative decrease in haemoglobin levels, transfusion rate, complication rate and length of postoperative hospital stay.ResultsA total of seven RCTs were included in the study, with clinical data reported for 697 patients. The overall access time was approximately 110 s shorter in the OSD group than in the serial dilation group (MD, −110.14; 95% CI −161.99 to −58.30; p<0.0001). The fluoroscopy time was shorter with OSD in all RCTs. In addition, the decrease in postoperative haemoglobin levels was approximately 2.3g/L less in patients in the OSD group than in those in the serial dilation group (MD, −0.23; 95% CI−0.39 to −0.07; p=0.004). No relationship was found between the successful dilation rate, stone-free rate, transfusion rate, or complication rate and the method of tract dilation.ConclusionOSD is a safe and efficacious tract dilation technique that can reduce the access time, fluoroscopy time and postoperative decrease in haemoglobin level. No difference was found in the successful dilation rate, stone-free rate, transfusion rate or rate of complications between the OSD and serial dilation groups. The difference in the length of postoperative hospital stay was uncertain. OSD may be a better method of tract creation for PCNL.

Objective: This study aims to compare outcomes of supine percutaneous nephrolithotomy to prone percutaneous nephrolithotomy as a traditional approach in Hasan Sadikin Hospital Bandung. Material & Methods: Data was taken from urology’s database between 2003-2012, which contain data of prone position (2003-2007), and supine position (2008-2012). Three hundred forty-nine patients were included in this study. We reviewed data on demography, stone burden, operating time, stone-free rate, transfusion rate, hospital stay, and major complications. Results: Of 174 patients underwent prone position, and 175 patients were part of the supine position. Age means of prone position was 51.0 years old, the supine position was 50.5 years old. The number of male patients was 65.5% for prone, and 66.1% for supine. The mean stone's largest diameter of prone was 23.87 mm, supine was 22.36 mm. The operating time of prone was 107 minutes; supine was 90 minutes. The stone-free rate of prone was 94.7%; supine was 91.3%. The mean hospital stays of prone was 14.3 days; supine was 9.6 days. The transfusion rate of prone position was 8.9%, supine was 7.2%. No major complications were recorded. Conclusion: Higher stone-free rates are achieved with patients in the prone position during PCNL. Supine position has shorter operating time, and hospital stay, lower blood transfusion rates. The complication rate is not different between the two positions.

OBJECTIVEDespite increasing adoption of endoscopic techniques for repair of nonsagittal single-suture craniosynostosis, the efficacy and safety of the procedure relative to established open approaches are unknown. In this systematic review the authors aimed to directly compare open surgical and endoscope-assisted techniques for the treatment of metopic, unilateral coronal, and lambdoid craniosynostosis, with an emphasis on quantitative reported outcomes.METHODSA literature search was performed in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Relevant articles were identified from 3 electronic databases (MEDLINE, EMBASE, and CENTRAL [Cochrane Central Register of Controlled Trials]) from their inception to August 2017. The quality of methodology and bias risk were assessed using the Effective Public Health Practice Project (EPHPP) Quality Assessment Tool for Quantitative Studies.RESULTSOf 316 screened records, 7 studies were included in a qualitative synthesis of the evidence, of which none were eligible for meta-analysis. These reported on 111 unique patients with metopic, 65 with unilateral coronal, and 12 with lambdoid craniosynostosis. For all suture types, 100 (53%) children underwent endoscope-assisted craniosynostosis surgery and 32 (47%) patients underwent open repair. These studies all suggest that blood loss, transfusion rate, operating time, and length of hospital stay were superior for endoscopically treated children. Although potentially comparable or better cosmetic outcomes are reported, the paucity of evidence and considerable variability in outcomes preclude meaningful conclusions.CONCLUSIONSLimited data comparing open and endoscopic treatments for metopic, unilateral coronal, and lambdoid synostosis suggest a benefit for endoscopic techniques with respect to blood loss, transfusion, length of stay, and operating time. This report highlights shortcomings in evidence and gaps in knowledge regarding endoscopic repair of nonsagittal single-suture craniosynostosis, emphasizing the need for further matched-control studies.

Background and Objectives. The null hypothesis of this study was that TA has no effect on postsurgical bleeding in patients undergoing TKA. Methods. This study was a double-blind randomized trial. In the first group (T) patients received 500 mg of intravenous Tranexamic acid (TA) twice (once preoperatively and once 3 hours postoperatively) and in the second group (P) they received slow infusion of normal saline as placebo. The primary outcome of the study was the level of Hb 48 hours after surgery. Results. Hb levels 48 hours after surgery as the primary outcome were 10.92±0.97 and 10.23±0.98 (g/dL) in groups T and P, respectively, and the difference was statistically significant (P=0.001). Statistically significant differences were also observed in Hb levels 6 and 24 hours after surgery, the drain output 48 hours after surgery, and the number of units of packed cells transfused between study groups (P<0.05). There was no significant difference in duration of hospitalization between the study groups (P = n.s.). Conclusions. The low dose perioperative intravenous TA significantly reduces blood loss, requirement for blood transfusion, and drain output in patients undergoing TKA. However, duration of hospitalization did not change significantly.

Abstract Background: Minimally invasive surgery includes percutaneous endoscopic lumbar discectomy and the microscopic tubular technique. This study aimed to compare the two techniques and evaluate the outcomes of the procedures.Methods: We retrospectively analyzed patients with far-lateral lumbar disc herniation (FLLDH) from June 2015 to October 2018. Twenty-six patients underwent paraspinal muscle-splitting microscopic-assisted discectomy (MD) and 30 patients underwent percutaneous endoscopic lumbar discectomy (PELD) surgery by the same surgical team. Data included the duration of the operation, duration of intraoperative radiation exposure, and average duration of hospitalization. Pre- and postoperative pain scores and neurological functions were recorded using a visual analog scale (VAS) score and Oswestry disability index (ODI).Results: 56 patients remained in the study over the 12–24 months period. The mean operating time was 65.83 ± 16.64 min in the PELD group, mean duration of radiation exposure was 2.87 ± 1.19 min, and average of hospitalization was 3.43 days. The mean operating time was 44.96 ± 16.87 min in the MD group, duration of radiation exposure was 0.78 ± 0.32 min, and duration of hospitalization was 4.12 days. There were two patients with postoperative transient dysesthesia and one underwent reoperation 7 months after surgery in the PELD group. One patient had postoperative transient dysesthesia in the MD group. Except low back pain at 3 months (p >0.05), all patients in both groups showed significant improvement in VAS and ODI scores compared with pre-operation and until final follow-up (p<0.05). Although the learning curve of MD is shorter compared with the PELD, beginners should practice on cadavers and receive teaching demonstrations from senior surgeons.Conclusion: Both techniques are minimally invasive, effective, and safe for treating far-lateral lumbar disc herniation in selected patients. Compared with the PELD technique, the MD procedure offers a wider field of vision during operation, shorter operation time, fewer postoperative complications, and shorter learning curve.

Abstract Purpose: To evaluate the aspects affecting transfusion following percutaneous nephrolithotomy (PCNL).Background: From 2016 to 2019, 665 patients underwent PCNL for removal of renal calculi in our center. Complications, including hemorrhages, have been reported. Twenty-three patients (3.5%) have received a blood transfusion and twelve (1.9%) were treated by hyper-selective embolization. We focus on the influencing factors related to postoperative blood transfusion. The factors analyzed were (age, sex, hypertension, diabetes, serum creatinine level, preoperative hemoglobin, and use of anticoagulants or antiplatelet medications); renal and stone factors (previous surgery, abnormal anatomy, stone side, stone burden, stone type); and surgical features: (access number, the calyx of puncture and stone-free rate). These data were analyzed for the presence of bleeding.Results: Among individual factors, preoperative hemoglobin level (P<0.001), and urinary infection (P<0.001) were significantly correlated with blood transfusion. Among renal and stone factors, only previous history of open surgery was significantly correlated with blood transfusion (P<0.05). Stone type or stone burden does not correlate with transfusion. There was also no statistically significant correlation between surgical features and bleeding, and a lower stone-free rate reported for transfusion group.Conclusion: The obtained results demonstrated that PCNL is a safer surgery in a high volume center, but anemic conditions, infections and history of open surgery will significantly increase transfusion rate following PCNL.

Objective: To report initial experience of laparoscopic radical prostatectomy (LRP) in Jakarta and evaluate the functional and oncology outcome. Material & Method: Between June 2007 until September 2008, we had done 9 times LRP surgery. All data is retrospectively taken and divided in three groups, i.e. pre-operative data (patient demography, pre-operative PSA, prostate volume, Gleason Score, clinical and functional staging), intra-operative data (intra-operative complication, conversion to open surgery, bleeding volume, and operating time), and post-operative data (post-operative complication, duration of urine catheter usage, duration of hospitalization, functional and oncology status). Results: Among nine subjects who underwent LRP, five subjects (55,55%) did not converted into open surgery. There are 2 subjects who gain their sexual potency and urine continence in one year post op. Only one subject is proven without biochemical failure in 1 year. Conclusion: We confirmed that radical prostatectomy can be performed with transperitoneal laparoscopic technique by a team that has been experienced in laparoscopic. Keywords: Laparoscopic radical prostatectomy, functional result, oncological result.
