Abstract Background: The study aims to compare the adequacy, complication rate and pathological classification when using 18G vs. 16G needles to perform renal biopsy with ultrasound-guidedance on native kidneys in Chinese individuals.Methods: We retrospectively analyzed the number of glomeruli, adequate sample rates, complication rates and pathological classification in 270 patients with the use of 18G or 16G needles from January 2011 to May 2017 and verified whether the needle gauge affected the disease diagnosis.Results: A total of 270 kidney biopsies were performed. Among them,72 were performed with 18G needles, and 198 were performed with 16G needles. There was no difference in the number of glomeruli under light microscope using 18G relative to 16G needles (24±11 vs. 25±11, p=0.265), whereas more glomeruli were found in the 16G group than in the 16G group using immunofluorescence microscopy (3±2 vs. 5±3, p<0.05). There was no significant difference in the adequate sample rates between the 18G group and the 16G group (90.28% vs. 93.94%, p=0.298). Minor complications including the incidence of lumbar or abdominal pain (4.17% vs. 7.07%, p = 0.57), gross hematuria (4.17% vs. 3.54%, p = 0.729), and perinephric hematoma without symptoms (4.17% vs. 1.52%, p = 0.195), were not significantly different between the 18G and 16G groups. In the 16G group, 2 cases of serious complications occurred: severe gross hematuria requiring blood transfusion and retroperitoneal hematoma requiring surgery. No serious complications were observed in the 18G group, although there was no significant difference in serious complications rates between the 18G and 16G groups (0% vs. 1.02%, p = 1).Conclusion: There was no significant difference in the number of glomeruli, adequate sample rates, or complication rates when using 18G or 16G needles to perform renal biopsy, and the use of an 18G needle with a smaller diameter did not affect the pathological diagnosis or classification of IgA nephropathy and lupus nephritis.

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.

Background: Percutaneous renal biopsy is performed for diagnosis and prediction of prognosis of renal diseases. Adequacy of tissue and clinically significant bleeding are the main issues of the procedure. We aimed to compare these issues in renal biopsy by blind and real time ultrasound guided technique.Methods: It was a cross sectional, randomized study conducted between June 2016 to December 2016. In blind technique, marking for biopsy was done by ultrasound. Two attempts were performed for all and more if tissue was inadequate. Patients kept in bed rest for 24 hours, observed for post procedure hematuria and ultrasound done at 6 hours and 24 hours to diagnose perinephric hematoma.Results: Total 75 biopsies (blind = 37 and Ultrasound -guided = 38) were evaluated. Blind and Ultrasound-guided technique had significant difference of number of attempt (mean±SD) 2.4±0.6 and 2.1±0.3 (p<0.01) respectively with no difference of number of glomeruli in light microscopy. Bleeding complications were macroscopic hematuria (11(30%)vs15(40%)) and perinephric hematoma ( 5(13.5%)vs3(7.9%)) in blind and Ultrasound-guided technique respectively with no significant difference. Those patients who developed perinephric hematoma was observed in all at 6 hours.Conclusions: Ultrasound-guided technique of percutaneous renal biopsy is superior with fewer attempts and equivalent in adequacy of tissue and bleeding complication than blind technique.

Object The question of whether preoperative therapy with somatostatin analogs can improve surgical outcome in acromegaly has not been definitively answered. In this paper, the authors report the effects of preoperative treatment with somatostatin analogs in a large sample of patients with acromegaly. Methods Between 1990 and 2003, 399 consecutive patients with acromegaly underwent surgery at the Istituto Scientifico San Raffaele. Thirty-three patients who had previously undergone surgery or radiation treatment, 48 patients treated with somatostatin analogs for fewer than 3 months, and patients who had stopped therapy for too long a time before surgery were excluded from the study. One hundred forty-three patients who had received somatostatin analogs prior to surgery (Group 1) were randomly matched to 143 patients who had never been treated with somatostatin analogs (Group 2). Matching criteria were tumor size and invasiveness into the cavernous sinus. Before surgery, Group 1 patients showed reduction of growth hormone levels to less than 50% of baseline in 64% of cases, but insulin-like growth factor–I was normalized in only 19.5%. Surgical remission occurred in 81 Group 1 patients (56.6%) and in 91 Group 2 patients (63.6%; p = 0.28). No significant difference in the remission rate was observed when cases were analyzed according to tumor size or invasiveness. Logistic regression analysis confirmed that pretreatment with somatostatin analogs was not associated with surgical outcome. Surgical morbidity was mild and similar in Group 1 and Group 2 patients (7 and 5.6%, respectively; p = 0.81). Surgical remission and complication rates in patients with acromegaly who received treatment with somatostatin analogs prior to surgery were not significantly different from those of matched patients who did not receive these agents. Conclusions At present, the routine use of presurgical therapy with somatostatin analogs for patients with acromegaly cannot be recommended.

The relative merits and efficacy of open versus closed mitral valvotomy remains controversial. The purpose of this study was to compare improvement of the hemodynamic parameters and exercise tolerance capacity of the 2 operations in 59 patients with pure mitral stenosis in sinus rhythm. Patients were randomly assigned to 1 of 2 groups: 29 patients in group 1 were operated on with the closed technique and 30 patients in group 2 were operated by the open technique. Preoperatively, the hemodynamic parameters and exercise capacity were similar in the two groups. Cardiac catheterization and exercise treadmill test were performed on all patients before and 3 months after each operation. Hemodynamic parameters as well as exercise tolerance capacity were significantly improved by both open and closed valvotomy ( p < 0.0001). However, postoperatively the improvement in exercise capacity was similar in both groups ( p = NS) and there was no significant difference in hemodynamic parameters in both groups, except for reduction in pulmonary artery pressure and increment in cardiac output. Complication rates were similar in both groups, except for atrial arrhythmias, which were more common in group 2. This study suggested that the closed technique, when performed by experienced surgeons, achieved similar hemodynamic and functional results as the open method. It also has the potential advantage of cost savings in addition to avoiding the complications of cardiopulmonary bypass. It clearly has a place in properly selected patients with mitral stenosis.

Background: The application of the Floating Mass Transducer (FMT) of a Vibrant Soundbridge (VSB) to the short incus process is intended to reduce both the surgery time and the complication and revision rate compared to other forms of application. In addition to collecting these parameters, the aim of this study is to investigate the primary audiological outcome of patients with an FMT application to the short process compared to the conventional methods. Methods: The present study retrospectively examined a total of n=36 patients who received a VSB between 01/2015 and 08/2018 at the ENT University Hospital Leipzig. In n=12 patients (group 1) the FMT was coupled to the short process, in n=24 patients (group 2) to other ear structures. The audiological results were evaluated pre- and postoperatively in the pure tone audiogram according to the recommendations of the AAO-HNS (1995) and the intelligibility (Freiburger, monosyllabic) was measured at 65 dB in the speech audiogram. In addition, the revision and complication rates as well as the surgical time were evaluated. Results: The audiological outcome of group 2 was significantly better postoperatively in both the pure tone (p<.001) and speech audiogram (p=.012). The surgery time of group 1 was significantly shorter (p=.002), but with a slightly increased revision rate (p=.519). The complication rate of group 2 was slightly higher, with no statistically significant difference to group 1 (p=.185). Conclusions: The FMT application on the short ambos process does not seem to offer any advantage in terms of audiological outcome, but at the same time is associated with a significantly shorter surgery time. There are no statistically significant differences in revision and complication rates.

Objectives: The aim of this study was to compare clinical outcomes and complication rates associated with semirigid (malleable) and inflatable penile prostheses (PPs) and investigate the factors that influence these complications. Material and methods: The records of 131 patients who had undergone penile prosthesis implantation (PPI) in our clinic due to erectile dysfunction (ED) between January 2010 and March 2019 were retrospectively reviewed. The initial surgery included 116 primary implants and 15 men had two revision operations. Patients were assigned to two groups as semirigid (malleable) PPI (group 1) and inflatable PPI (group 2) patients, and obtained data were compared across these two groups. Results: Group 1 included 93 patients, while Group 2 included 38 patients. Postoperative complication rates of Group 1 were 8.6% (n = 8), and Group 2 were 21% (n = 8), and the comparison of postoperative complication rates revealed a statistically significant difference between the two groups (p = 0.025). The majority of these complications (50%) was constituted by mechanical failure associated with inflatable PPs. When patients were further segregated as those with and without diabetes type 2 (DM) and those who had and had not undergone radical pelvic surgery (RPS), the comparison of complication rates across these subgroups did not yield any significant difference. Conclusions: We determined in this study that semirigid (malleable) PPs were associated with lower complication rates compared to the inflatable group, particularly with regard to mechanic failure, and that DM and history of RPS did not make a difference in complication rates in patients planned to undergo PPI.

Objective This study evaluated the effect of low-energy radiofrequency thermocoagulation added to standard liquid sclerotherapy on clinical outcomes of patients with venous insufficiency. Patients and method We included 111 patients with spider veins CEAP/C1 stage. The patients were randomized into sclerotherapy (Group 1) and sclerotherapy + sclerotherapy immediately followed by low energy percutaneous RF thermocoagulation (Group 2) groups and followed up with same protocols prospectively. Results The study groups did not differ in terms of the mean age, body mass index, the number of spider veins and pre-interventional venous clinical severity scores (VCSS). Patients' self-assessed satisfaction ratings of cosmetic outcomes were found to be higher compared to the baseline (p = 0.001). While both techniques caused a significant decline in VCSS at postprocedural third month, it was observed that the type of applied intervention did not affect the VCSS (p = 0.43 and p = 0.93, respectively). There was a significant difference in hyperpigmentation and trapped blood between the two groups after the procedure (p = 0.009 and p = 0.02, respectively), there was no statistically significant difference in terms of skin necrosis (p = 0.52). A significant difference in the self-assessed cosmetic outcomes was observed in patients treated with sclerotherapy followed by low energy percutaneous RF thermocoagulation compared with patients whom sclerotherapy performed alone (p = 0.001). Discussion This study suggests that radiofrequency thermocoagulation added to the sclerotherapy provides better cosmetic outcomes with less treatment sessions and no additional complication rates.
