Despite improvements of strategy in radical retropubic prostatectomy, blood loss is still a major concern. The lymphocyte/monocyte (LM) ratio is a prognostic indicator for various diseases. We identified the risk factors, including the LM ratio, for red blood cell (RBC) transfusion during radical retropubic prostatectomy. This retrospective study assessed patients who underwent radical retropubic prostatectomy between March 2009 and December 2020. To determine the risk factors for RBC transfusio...

Many studies have investigated the prognostic significance of peripheral blood parameters—including lymphocyte-to-monocyte ratio (LMR)—in several cancers in recent decades. We evaluated the prognostic factors for five-year tumor recurrence after the transurethral resection of a bladder tumor (TURBT). In total, 151 patients with non-muscle invasive bladder tumors who underwent TURBT under spinal anesthesia were selected for this retrospective analysis. The time to tumor recurrence was determined ...

Acute kidney injury (AKI) is related to mortality and morbidity. The De Ritis ratio, calculated by dividing the aspartate aminotransferase by the alanine aminotransferase, is used as a prognostic indicator. We evaluated risk factors for AKI after radical retropubic prostatectomy (RRP). This retrospective study included patients who performed RRP. Multivariable logistic regression analysis and a receiver operating characteristic (ROC) curve analysis were conducted. Other postoperative outcomes we...

Computed tomographic coronary angiography (CTCA) has prognostic value for early major adverse cardiac events (MACEs) after liver transplantation. However, the association between CTCA and long-term MACEs in liver transplant (LT) recipients remains unknown. We evaluated the association between CTCA and long-term MACEs within 5 years after living donor liver transplantation (LDLT). A total of 628 LDLT recipients who underwent CTCA were analyzed between 2010 and 2012. MACEs were investigated within...

Background Robot-assisted laparoscopic prostatectomy (RALP) frequently entails postoperative pulmonary complications (PPCs) due to the Trendelenburg position and pneumoperitoneum. Diaphragm thickening fraction (TF) as an imaging marker can offer the advantage of predicting respiratory outcomes. Therefore, we evaluated the effect of diaphragm TF on the occurrence of PPCs in RALP. Methods We measured the preoperative thickness of the diaphragm at peak inspiration (Tpi) and end expiration (Tee) usi...

PURPOSE Robot-assisted laparoscopic prostatectomy (RALP) requires particular surgical conditions, such as carbon dioxide pneumoperitoneum and steep Trendelenburg positioning, which may have adverse effects on the respiratory system. The effect of sugammadex on postoperative pulmonary complications (PPCs) is controversial. Therefore, we evaluated the incidence of PPCs according to the type of neuromuscular blockade reversal agents in RALP. METHODS We retrospectively analyzed RALP patients. We com...

Background A laryngeal mask airway (LMA) is usually inserted by conventional 7 cm head elevation. However, little is known about the association of head elevation degree and LMA insertion. We hypothesized that 14 cm head elevation would increase the first attempt success rate of LMA Supreme insertion compared with conventional 7 cm head elevation in patients undergoing transurethral resection of bladder tumour. Methods Patients were randomly allocated to the high group (n = 55, 14 cm head elevat...

Radical cystectomy is a standard treatment for muscle-invasive bladder cancer but frequently entails postoperative pulmonary complications (PPCs). Nutrition is closely associated with postoperative outcomes. Therefore, we evaluated the impact of preoperative prognostic nutritional index (PNI) on PPCs in radical cystectomy. PNI was calculated as 10 × (serum albumin) + 0.005 × (total lymphocyte count). The risk factors for PPCs were evaluated using multivariate logistic regression analysis. A rece...

Abstract Background Burn is an overwhelming injury. The De Ritis ratio, defined as aspartate aminotransferase to alanine aminotransferase ratio, can be used to predict poor outcomes. We evaluated the risk factors, including the De Ritis ratio, associated with 1-year mortality after burn surgery. Methods Patients who underwent burn surgery from 2009 to 2019 were retrospectively evaluated. Multivariate Cox regression analysis was conducted to evaluate the risk factors for 1-year mortality after bu...

Background Burn injury in elderly patients can result in poor outcomes. Prognostic nutritional index (PNI) can predict the perioperative nutritional status and postoperative outcomes. We aim to evaluate the risk factors, including PNI, for one-year mortality after burn surgery in elderly patients. Methods Burn patients aged ≥65 years were retrospectively included. PNI was calculated using the following equation: 10 × serum albumin level (g/dL) + 0.005 × total lymphocyte count (per mm3). Cox regr...
