A successful staged Fontan operation for a right atrial isomerism neonate having major aortopulmonary collateral arteries and extracardiac total anomalous pulmonary venous connection

Right atrial isomerism and pulmonary atresia combined with major aortopulmonary collateral arteries are very rare. Surgical treatment becomes more challenging when an extracardiac total anomalous pulmonary venous connection (TAPVC) requiring surgical repair neonatally is also present. We describe a successful staged Fontan operation for a neonate with a single ventricle, right ...

Background To investigate the impact of biological gender on operative parameters, especially operative time, in laparoscopic partial nephrectomy (LPN) for T1 renal tumor. Methods One hundred and eleven (28 female and 83 male) patients and 64 (20 female and 44 male) patients with renal tumors suspected to be RCC cT1aN0M0 who underwent retroperitoneal and transperitoneal LPN, ...

Developing a preoperative predictive model for ureteral length for ureteral stent insertion

Background Ureteral stenting has been a fundamental part of various urological procedures. Selecting a ureteral stent of optimal length is important for decreasing the incidence of stent migration and complications. The aim of the present study was to develop and internally validate a model for predicting the ureteral length for ureteral stent insertion. Methods This study included ...

Modification of hemi-Fontan operation for patients with functional single ventricle and anomalous pulmonary venous connection to the superior vena cava: mid-term results†

OBJECTIVES Fontan candidates with mixed totally anomalous pulmonary venous connection often have postoperative pulmonary venous obstruction after cavopulmonary anastomosis. Because some pulmonary venous obstructions have no intimal hypertrophy at reoperation, we considered such pulmonary venous obstructions to be caused by 3D deformities arising from dissection or mobilization of ...

Bone management in Japanese patients with prostate cancer: hormonal therapy leads to an increase in the FRAX score

Background Osteoporosis is a common consequence of androgen deprivation therapy (ADT) for prostate cancer. Up to 20 % of men on ADT have suffered from fractures within 5 years. The WHO Fracture Risk Assessment Tool (FRAX) has been utilized to predict the 10-year probability of major osteoporotic and hip fracture. However, to date, no large studies assessing the utility of the FRAX ...

Pretreatment neutrophil-to-lymphocyte ratio predicts the prognosis in patients with metastatic prostate cancer

Background The neutrophil-to-lymphocyte ratio (NLR), a simple marker of the systemic inflammatory response in critical care patients, has been suggested as an independent prognostic factor for several solid malignancies. We investigated the utility of pretreatment NLR as a prognosticator in patients who presented with metastatic prostate cancer. Methods We first investigated the ...

Increased neutrophil-to-lymphocyte ratio is associated with disease-specific mortality in patients with penile cancer

Background The neutrophil-to-lymphocyte ratio (NLR), a simple marker of the systemic inflammatory response, has been demonstrated to correlate with patient outcomes for various solid malignancies. We investigated the utility of the pretreatment NLR as a prognosticator in patients who presented with penile cancer. Methods A total of 41 patients who underwent complete blood count ...

Neutrophil-to-lymphocyte ratio is a prognostic marker in bladder cancer patients after radical cystectomy

Background There is no reliable biomarker for predicting the prognosis of patients who undergo radical cystectomy for bladder cancer. Recent studies have shown that the neutrophil-to-lymphocyte ratio (NLR) could function as a useful prognostic factor in several types of malignancies. This study aimed to assess the usefulness of NLR in bladder cancer. Methods A total of 74 patients ...

Discolored Ureteral Stents: Findings in Urinalysis and Urine Culture

Objective Discolored ureteral stents are sometimes encountered in daily clinical practice; however, the mechanism(s) underlying the development of discolored ureteral stents remain unknown. In this study, we retrospectively analyzed the characteristics of discolored ureteral stents based on the results of a urinalysis and urine culture. Materials & Methods We identified a total of ...

Ureteroscopy-assisted retrograde nephrostomy for a large and obstructive renal pelvic stone: a case report

Introduction We have previously described the use of ureteroscopy-assisted retrograde nephrostomy. However, reaching the target calyx with the ureteroscope is difficult in patients with obstructive renal pelvic stones. Case presentation A 53-year-old Japanese woman was referred to our department for the treatment of a right renal stone. She was admitted to our department for ...

Fontan operation for the Cantrell syndrome using a clamshell incision

A median sternotomy could be difficult for a child with ectopia cordis and complex congenital cardiac anomalies. We report a patient with ectopia cordis, functionally single ventricle and bilateral superior vena cava, who underwent a staged Fontan procedure through a clamshell incision and the sternothoracotomy approach.

Utility and Limitation of Cumulative Stone Diameter in Predicting Urinary Stone Burden at Flexible Ureteroscopy with Holmium Laser Lithotripsy: A Single-Center Experience

Purpose To retrospectively assess the clinical utility in ureteroscopy (URS) planning of cumulative stone diameter (CSD), which does not account for stone width or depth, as a predictor of URS outcome and compare it with stone volume. Materials and Methods Patients with renal stones treated at a single institute by flexible URS were retrospectively evaluated. To assess the clinical ...

Technical modification enabling pulmonary valve-sparing repair of a severely hypoplastic pulmonary annulus in patients with tetralogy of Fallot†

OBJECTIVES Although pulmonary valve-sparing repair is preferable for patients with tetralogy of Fallot, the repair of very small pulmonary valves is challenging. The present study evaluates our modification for preserving severely hypoplastic pulmonary valves in patients with tetralogy of Fallot.
