Purpose. To ascertain whether retrograde intrarenal surgery (RIRS) is as effective in patients treated previously with open renal stone surgery (ORSS) on the same kidney as in patients with no previous ORSS.Methods. There were 32 patients with renal stones who had previous ORSS and were treated with RIRS in the study group (Group 1). A total of 38 patients with renal stones who had no previous ORSS and were treated with RIRS were selected as the control group (Group 2). Recorded data regarding preoperative characteristics of the patients, stone properties, surgical parameters, outcomes, SFRs (no fragments or small fragments <4 mm), and complications between groups were compared.Results. Mean age, mean BMI, mean hospital stay, and mean operative time were not statistically different between groups. Mean stone size (10.1 ± 5.6 versus 10.3 ± 4.2;p=0.551) and mean stone burden (25.4 ± 14.7 versus 23.5 ± 9.9;p=0.504) were also similar between groups. After the second procedures, SFRs were 100% and 95% in groups 1 and 2, respectivelyp=0.496. No major perioperative complications were seen.Conclusion. RIRS can be safely and effectively performed with acceptable complication rates in patients treated previously with ORSS as in patients with no previous ORSS.

<p><strong>Introduction:</strong> Our aim was to demonstrate the effect of insicion of renal parenchyma during open renal stone surgery (ORSS) on percutaneous nephrolithotomy (PNL) outcomes.</p><p><strong>Methods:</strong> Patients with history of ORSS who underwent PNL operation between June 2005 and June 2015 were analyzed retrospectively. Patients were divided into two groups according to their type of previous ORSS. Patients who had a history of ORSS with parenchymal insicion, such as radial nephrotomies, anatrophic nephrolithotomy, lower pole resection, and partial nephrectomy, were included in Group 1. Other patients with a history of open pyelolithotomy were enrolled in Group 2. Preoperative characteristics, perioperative data, stone-free status, and complications were compared between the groups. Stone-free status was defined as complete clearance of stone(s) or presence of residual fragments smaller than 4 mm. The retrospective nature of our study, different experience level of surgeons, and lack of the evaluation of anesthetic agents and cost of procedures were limitations of our study.</p><p><strong>Results:</strong> 123 and 111 patients were enrolled in Groups 1 and 2, respectively. Preoperative characteristics were similar between groups. In Group 1, the mean operative time was statistically longer than in Group 2 (p=0.013). Stone-free status was significantly higher in Group 2 than in Group 1 (p=0.027). Complication rates were similar between groups. Hemorrhage requiring blood transfusion was the most common complication in both groups (10.5% vs. 9.9%).</p><p><strong>Conclusions:</strong> Our study demonstrated that a history of previous ORSS with parenchymal insicion significantly reduces the success rates of PNL procedure.</p>

Objective. Retrograde intrarenal surgery (RIRS) performed using a flexible ureterorenoscope marked the beginning of a new era in urology. Today, even staghorn stones are successfully treated via RIRS. The recommended treatment for larger stones is percutaneous nephrolithotomy (PNL). However, the question of whether PNL or RIRS should be the first-line treatment option for larger stones remains controversial. In this study, we contribute to the debate by comparing the success and complication rates of PNL and RIRS that were used to treat renal pelvis stones 2-3 cm in diameter.Materials and Methods. The medical records of 154 patients (74 PNL, 80 RIRS) were retrospectively evaluated. PNL patients were placed in Group 1 and RIRS patients in Group 2.Results. The complete stone-free rates were 95.5% in the PNL group and 80.6% in the RIRS group 1 month postoperatively (P=0.061). The respective complication rates (evaluated using the Clavien system) were 13.5% and 8.8% (P=0.520).Conclusions. RIRS affords a comparable success rate, causes fewer complications than PNL, and seems to be a promising alternative to PNL when larger stones are to be treated. Prospective randomized controlled trials are needed to confirm these findings.

Introduction: This study aims to investigate the outcomes and complication rates of patients undergoing retrograde intrarenal surgery (RIRS) at the live surgery events organized as boutique course series. Materials and Methods: Eight RIRS courses were organized between November 2017 and February 2020. Data of 24 patients who were operated in the live surgery events (as LSE group) for renal stone were matched with the data of 24 substitute patients (as control group) who underwent regular RIRS on the same period at the same centers.. Results: Stone free status of groups was similar (88% in LSE and 79% in the control group; p=1). There was no significant difference in terms of complication and need for additional procedure rates, operation and fluoroscopy and hospitality times between the two groups (p=1, p=1, p=0.12, p=0.58 and p=0.94, respectively). Fifty-four % (13/24) of LSE operations were performed by guest surgeons. No statistically significant difference was found between the patients who operated by host and guest surgeons. However, the operation times of the operations performed by guest surgeons were longer than those performed by the host surgeons (96.5±28 and 66.5±30 minute, respectively, p=0.07). Conclusion: Our study is the first report on this area. RIRS live surgery can be performed with low complication and high stone-free rates without jeopardizing patient safety. If the surgeon is not familiar with the operating room set-up or staffs, the live surgery must performed by the host surgeon to avoid extended operating time.

The purpose of our study is to determine whether bucco-palatal/lingual (BPL) root dilacerations (RD), especially in single root teeth, can be determined using the ImageJ program through only one periapical radiography. Extracted teeth without any RD ( n = 8) were determined as the control group (Group 1) and with RD in apical 1/3 part at least 20° with the longitudinal axis in the BPL direction ( n = 8) as the study group (Group 2). With the help of a simple holder system prepared, digital periapical radiographs of all teeth were taken in an anteroposterior position. Histogram analysis of all periapical radiographs was performed using the spectrum feature of ImageJ software. It was aimed to make a dilaceration analysis by comparing the groups using mean, standard deviation, minimum, maximum, and bin width values. As a result of the Mann-Whitney U test, all mean and maximum values showed a statistically significant difference between the study and control groups ( p < 0.05). This pilot study revealed that the ImageJ software can be used to diagnose BPL dilaceration in the apical 1/3 part of the root. It is important for dentists and patients that it can contribute to limiting the radiation dose to which patients will be exposed.

The study presents the results of quality assessment of antiischemic myocardial protection by low- volume method of cardioplegia by «Custodiol» solution during operations with cardiopulmonary by- pass. The study involved 57 patients who underwent different cardiosurgery operations with cardio- pulmonary bypass. The patients were divided into two groups on the basis of the volume of cardioplegic solution. Research group (Group № 1) consists of 33 patients who were administered «Custodiol» in low volume limited by 1000 ml. The control group (Group № 2) consists of 24 patients who were ad- ministered standart volume of the solution corresponding to the manufacturer's instructions: 1 ml per 1 g of myocardial mass during 6-8 minutes. The results has indicated that the use of low volume of car- dioplegic «Custodiol» in a single administration manner provides a complete antiischemic protection of the myocardium during the correction of valvular heart disease, including combination with coronary artery bypass grafting. usage of low volume «Custodiol» solution method does not increase the need of inotropic and vasopressor usage and pacing time. The use of low volumes of «Custodiol» helps to reduce transfusion requirements of blood and its components.

Aims A significant percentage of patients remain dissatisfied after total knee arthroplasty (TKA). The aim of this study was to determine whether the sequential addition of accelerometer-based navigation for femoral component preparation and sensor-guided ligament balancing improved complication rates, radiological alignment, or patient-reported outcomes (PROMs) compared with a historical control group using conventional instrumentation. Methods This retrospective cohort study included 371 TKAs performed by a single surgeon sequentially. A historical control group, with the use of intramedullary guides for distal femoral resection and surgeon-guided ligament balancing, was compared with a group using accelerometer-based navigation for distal femoral resection and surgeon-guided balancing (group 1), and one using navigated femoral resection and sensor-guided balancing (group 2). Primary outcome measures were Patient-Reported Outcomes Measurement Information System (PROMIS) and Knee injury and Osteoarthritis Outcome (KOOS) scores measured preoperatively and at six weeks and 12 months postoperatively. The position of the components and the mechanical axis of the limb were measured postoperatively. The postoperative range of motion (ROM), haematocrit change, and complications were also recorded. Results There were 194 patients in the control group, 103 in group 1, and 74 in group 2. There were no significant differences in baseline demographics between the groups. Patients in group 2 had significantly higher baseline mental health subscores than control and group 1 patients (53.2 vs 50.2 vs 50.2, p = 0.041). There were no significant differences in any PROMs at six weeks or 12 months postoperatively (p > 0.05). There was no difference in the rate of manipulation under anaesthesia (MUA), complication rates, postoperative ROM, or blood loss. There were fewer mechanical axis outliers in groups 1 and 2 (25.2%, 14.9% respectively) versus control (28.4%), but this was not statistically significant (p = 0.10). Conclusion The sequential addition of navigation of the distal femoral cut and sensor-guided ligament balancing did not improve short-term PROMs, radiological outcomes, or complication rates compared with conventional techniques. The costs of these added technologies may not be justified. Cite this article: Bone Joint J 2020;102-B(6 Supple A):24–30.

Purpose: To evaluate the true necessity of open end ureteral catheter insertion in patients with moderate to severe pelvicalyceal system dilation treated with percutaneous nephrolithotomy (PNL) under sonographic guidance. Patients and methods: 50 cases treated with PNL under sonographic guidance in prone position for solitary obstructing renal stones were evaluated. Patients were randomly divided into two groups; Group 1: Patients in whom a open end ureteral catheter was inserted prior to the procedure; Group 2: Patients receiving no catheter before PNL. In addition to the duration of the procedure as a whole and also all relevant stages as well, radiation exposure time, hospitalization period, mean nephrostomy tube duration, mean drop in Hb levels and all intra and postoperative complications have been evaluated. Results: Mean size of the stones was 308.5 ± 133.2 mm2. Mean total duration of the PNL procedure in cases with open end ureteral catheter was significantly longer than the other cases (p < 0.001). Evaluation of the outcomes of the PNL procedures revealed no statistically significant difference between two groups regarding the stone-free rates (86% vs 84%). Additionally, there was no significant difference with respect to the duration of nephrostomy tube, hospitalization period and secondary procedures needed, complication rates as well as the post-operative Hb drop levels in both groups (p = 0.6830). Conclusions: Our results indicate that the placement of an open end ureteral catheter prior to a PNL procedure performed under sonographic access may not be indicated in selected cases presenting with solitary obstructing renal pelvic and/or calyceal stones.

Purpose: To assess the effects of aprotinin on the formation and resolution of fat embolism of the lungs. Methods: The changes in arterial blood gas levels and perfusion scintigraphy were studied by forming experimental standardized fat embolism in rabbits with autogenous fat obtained from their femur medullas. Two groups, each consisting of 14 albino rabbits, were used in this study. Group 1, which received intravenous saline solution, was the control group. Group 2, which received aprotinin, was referred to as the aprotinin group. Autogenous femoral medullary content was used for embolization procedures. Arterial blood gas levels were recorded 72 hours before and 1, 24, 72 hours and 10 days following the embolization procedure. Pulmonary perfusion scintigraphies were performed 72 hours before the embolization procedure and on the first and 72nd hours, and the 10th day. Results: Fat embolism was achieved in all rabbits. Seven rabbits in the control group and one rabbit in the aprotinin group died within an hour after the embolization procedure. According to blood gas levels and perfusion scintigraphic findings, the aprotinin group significantly had less pulmonary fat embolism and recovered faster than the control group, especially during the first 24 hours. There was no significant difference in regression of pulmonary dysfunction between the two groups. Conclusion: The correlation between the blood gas levels and scintigraphic findings suggested that the administration of aprotinin for prophylactic purposes had favorable effects on the development of pulmonary gas exchange disturbance and perfusion defect in fat embolism.

<p><strong>OBJECTIVE:</strong> The objective of the study was to investigate the effect of immersion in water strategy during labor on postpartum bleeding by calculating the postpartum reduction rates of the hematocrit values of the patients.</p><p><strong>STUDY DESIGN:</strong> The study groups consisted of 84 women undergoing vaginal delivery with immersion in water during labor (group 1) and the control group (group 2) of 84 women undergoing normal vaginal delivery. Patients who have received additional medical and surgical interventions for alleviation of postpartum hemorrhage, patients who have undergone an episiotomy and/or perineal trauma were not included in the study. All data were taken from patients who have delivered with spontaneous vaginal delivery. Postpartum hematocrit fall rates of the groups have been compared and the effect of immersion in water on postpartum hemorrhage has been evaluated.</p><p><strong>RESULTS:</strong> The study groups consisted of 84 women undergoing vaginal delivery with immersion in water during labor (Group 1) and the control group (Group 2) of 84 women undergoing vaginal delivery at the hospital. The women in the two groups were matched with respect to age, parity, birth weight and gestational age. The mean age of the women was 29.8±4.8 and 30.5±4.9 respectively. The mean hematocrit difference in the first group was 2.08 ± 1.88 and in the second group was 3.81 ± 1.55. The mean percentage of hematocrit reduction in the first group was 5.71% and in the second group 10.23%.</p><p><strong>CONCLUSION:</strong> Our data showed that mean hematocrit level decreases among women following vaginal delivery more than women who give birth vaginally within immersion in water during labor. The percentage of hematocrit reduction in the water birth group was lower than in the control group. Water birth seems to facilitate uterine contractions more efficiently following vaginal delivery.</p>
