The aim of this study is to compare detrusor overactivity (DO) subtypes namely terminal (TDO) and phasic (PDO) in terms of frequency, etiologic reasons, urodynamic findings and relationships with neurological diseases. Patients' characteristics including age, gender, neurological diseases, were noted. Bladder volume on the first desire to voiding (FSD), the strong desire to voiding (SDV), maximum bladder capacity (MBC), bladder compliance (BC), presence and type of DO, and amplitude of DO (Ad) were also noted during the IUDS. Patients with TDO and PDO were compared in terms of patient characteristics, urodynamic parameters, and neurological diseases. 1018 patients were enrolled in the study. Neurological disease was noted in 180 patients; spinal cord trauma (SCT):46, Alzheimer Disease (AD):8, Parkinson's Disease (PD):12, spina bifida (SB):21, epilepsy (ED):18, cerebrovascular disease (CVD):20 and Multiple Sclerosis (MS):55. Urodynamic DO was observed in 882 patients (neurogenic-DO:149 and idiopathic-DO:733), (PDO:837, TDO:45). A significant difference was observed between the groups regarding the FSD, MBC and Ad (p=0.032, p=0.049 and p=0.001 respectively). However, no difference was observed in BC (p=0.510). The incidence of TDO and PDO was 6% and 5% for neurogenic-DO and 94% and 95% for the idiopathic-DO, respectively (p=0.327). Among the neurogenic diseases only patients with SCT had significant differences regarding type of DO (TDO 11.1%, PDO 3.1%) (p= 0.04). Neurogenic diseases are not a significant risk factor for TDO. Spinal cord trauma is associated with higher rates of TDO compared to other neurogenic diseases. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this study is to evaluate prediction of postoperative ureteral obstruction needing ureteral stent insertion by evaluating the resistive index (RI) values and the grade of hydronephrosis. Material and Methods: A total of 66 adult patients undergoing stentless endoscopic ureteral stone treatment (URS) between January 2018 and January 2019 were included in this prospective study. Preoperative patient and stone characteristics were noted. All patients were evaluated with renal Doppler ultrasonography study to assess degree of hydronephrosis and RI values. A renal Doppler ultrasonography was repeated at postoperative 1st, 3rd and 7th days. Changes in both RI and hydronephrosis levels before and after the procedures were noted. On the postoperative 7th day, patients were divided into two groups including obstructive and non-obstructive cases according to RI values assessed where a RI value of 0.7 was accepted as the cut-off for obstruction. The preoperative and perioperative characteristics of both groups were evaluated in a comparative manner. Results: The mean patient age was 43.6 ± 1.72 years. Significant improvements were noted in RI and grade of hydronephrosis after the operation. The grade of hydronephrosis and RI values were found to improve more significantly on postoperative 3rd day when compared to the postoperative 7th day (p < 0.01 and p < 0.01). A significant correlation was detected between the grade of hydronephrosis (>grade 2) and obstructive RI values (> 0.7) in each postoperative visits (p: 0.001). RI values (> 0.7) at postoperative seventh days were correlated with larger mean stone size, increased ureteral wall thickness, increased diameter of the ureter proximal to the stone, and longer duration of the operation. Preoperative high-grade hydronephrosis indicated obstructive RI values at postoperative seventh day (p = 0.001) Conclusion: Changes in RI values on Doppler sonography and the grade of hydronephrosis may be a guiding parameter in assessing postoperative ureteral obstruction.

The aim of the study was to determine different variables that may be predictive for prolonged lymporrhoea and duration of lymphatic drainage. Two hundred and three patients who underwent radical cystectomy (RC) and pelvic lymph node dissection (PLND) were enrolled in this study. Lymphorrhoea was defined as the total amount of lymph drained by the drains until their removal. Duration of drainage was defined as the days until the removal of the last drains. Parameters that might be related to lymphorrhoea and duration of drainage including age, body mass index (BMI), removed lymph nodes, hemoglobin level (gr/dl), estimated blood loss (ml) (EBL), platelet count (PLN), hospital stay (HS) and lymph node status were reviewed retrospectively. Statistical analyses were performed to determine the association between lymphorrhoea with probable predictors for these variables. The mean number of removed lymph nodes was 28.52 (16-58). The mean amount of lymphorrhoea and the duration of drainage were 1504 ml (300-5850) and 10.10 days (2-27), respectively. Multivariate analyses revealed that the mean amount of lymphorrhoea rises gradually as EBL, patients age, negative lymph nodes and lymphadenectomy extension increases (P<0.05). Related to the duration of drainage, multivariate analyses showed that BMI and the number of removed lymph nodes were statistically significant predictors of prolonged drainage (p=0.016, p=0.046; respectively). Predictors for lymphorrhoea may help us mainly to foresee the duration of the hospital stay and the eventual complications that may be induced by lymphorrhoea. In patients with a higher risk for lymphorrhoea, preoperative maneuvers could be applied to decrease lymphorrhoea. [ABSTRACT FROM AUTHOR]

We read the article entitled ''Retrograde Intrarenal Surgery vs. Percutaneous Nephrolithotomy vs. Extracorporeal Shock Wave Lithotripsy for Lower Pole Renal Stones 10-20 mm: A Meta-analysis and Systematic Review''  published in Urology Journal (1). The topic is still hot in urology regarding lower pole kidney stones in 10-20 mm diameters.  Although extracorporeal shock wave lithotripsy (ESWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) are the available options for the patients with lower pole renal stones 10-20 mm diameter, the decision making among the methods is still controversy. This manuscript is valuable in this regard.  At the present manuscript, the authors prepared a very comprehensive meta-analysis of existing evidence to quantify and compare the safety and efficacy of PCNL, RIRS and ESWL for lower pole renal stones 10-20mm.  They emphasized the longer operative time of PCNL and RIRS compared to ESWL. They also reported a higher stone-free rate, the lower retreatment rate and auxiliary procedure following PCNL with the longest hospital stay for PCNL.  When it comes to ESWL, the lowest SFR, the higher retreatment rate and auxiliary procedure rate, but a shorter operative time and the shortest hospital stay was reported. The authors indicated stone to skin distance (SSD) as an unfavourable factor for ESWL. This issue is also reported in current literature. SSD was calculated by measuring the distance from the stone to the skin in three angles (0°, 45° and 90°) and the cut-off value for SWL failure was reported in a wide-scale from 100 mm to 119 mm(2,3). At the present study, the authors presented 10 mm as a predictive value for the criteria of SWL failure. This statement seems to be not correct totally also 10 mm is an impossible value for SSD. In our opinion, it was caused by a misspelling, and a correction may be informative for the readers. [ABSTRACT FROM AUTHOR]

Purpose: To compare 90-day  perioperative complications and pathological outcomes between laparoscopic radical cystectomy (LRC) and extraperitoneal radical cystectomy (EORC) approaches., Materials and Methods: All operations were performed in a single high-volume tertiary referee center by the same surgical team.Males ≥ 18 years with pre-cystectomy clinical T1-T3 disease and having undergone an ileal conduit were included. Exclusion criteria included patients with inflammatory bowel disease, previous pelvic and/or abdominal irradiation, neo-adjuvant chemotherapy, and/or clinical T4 disease. Perioperative outcomes such as operative time, estimated blood loss, transfusion rate, hospital stay, and 90-day complications were evaluated. The recovery duration of regular bowel activity, mean stool passage,and ileus rates were recorded., Results: A total of 221 patients met the inclusion criteria(81 LRC and 130 EORC). Demographics and preoperative parameters were comparable. Intraoperative estimated blood lossfavored LRC by a median of 450 mL (200-900) P=.021) vs. a median of 700 mL (300-2900) for EORC. The transfusion rate did not differ between the two groups; %14.8 (N=12) for the LRC and %20.8 (N=27) for EORC (P=.37). The median hospital stay was 9 (4-49) days for EORC and 8 (4-29) days for LRC (P=.011). The need for analgesics to control pain through an epidural catheter was higher for EORC (P=.042). There was no difference in overall complication rates (P=.47)., Conclusion:   Although LRC appears to have a slight advantage over EORC, both techniques yield satisfactory results in regard to ileus rates and 90-day perioperative complications.
