There are inconsistent results pertaining to risk factors for venous thromboembolism (VTE) in patients following urologic surgeries. We attempted to establish a visualization model to shed further light upon this topic. Consequently, a total of 436 patients who were tested for VTE following urologic surgeries were retrospectively enrolled. Least absolute shrinkage and selection operator method (LASSO) method was utilized to determine risk factors for VTE and a subsequent nomogram was constructed. The concordance index (C-index) and calibration curve were utilized to evaluate the nomogram. The results suggested that age, history of smoking, D-dimer levels on the first postoperative day, transfusion volume and body mass index (BMI) were identified as significant risk factors for VTE. The C-index of the nomogram composed of the five variables was 0.747 (95% CI 0.700-0.793) and the calibration plot demonstrated good performance. Therefore, the present nomogram could predict the risk of VTE following urologic surgeries.

Lateral decubitus: its influence on hemodynamic and respiratory function during retroperitoneal robotic assisted laparoscopic pyeloplasty (R-RALP) in children.
J Robot Surg

Department of Pediatric Anesthesia and Intensive Care, Necker-Enfants Malades University Hospital, AP-HP Centre, Université Paris Cité, 149, Rue de Sèvres 75015, Paris, France.
Retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP) is the commonest urologic procedure performed in children, entailing retroperitoneal CO2 insufflation and lateral decubitus, whose effects on cardiopulmonary variables are poorly known. We, therefore, studied hemodynamic and respiratory changes due to CO2 insufflation and lateral decubitus in children undergoing R-RALP and their effects on regional tissue oxygenation. Between 1/2021 and 7/2024, children affected by ureteropelvic joint obstruction (UPJO) underwent a pyeloplasty by R-RALP at Necker Enfants Malades Hospital (Paris, France), using a standardized surgical technique and a lung-protecting anesthetic protocol aimed to prevent hypercarbia.

Department of Urology, Peking University People's Hospital, Beijing, 100044, China.
Purpose: This study aims to elucidate the role of pituitary adenylate cyclase-activating polypeptide (PACAP) in Hunner-type Interstitial Cystitis (HIC) and evaluate its potential as a therapeutic target.
Methods: Bladder tissue samples were obtained from HIC patients and normal bladder tissue from bladder cancer patients. PACAP expression was assessed through immunohistochemistry.
The ratio of COL2A1:COL1A1 in dartos tissue patients with hypospadias.
BMC Urol
January 2025
Urology Department HOGIP UCAD, Cheikh Anta Diop University, Dakar, Senegal.
Background: The inelasticity of dartos tissue and the regulation of collagen expression are significant factors in the pathophysiology of chordee associated with hypospadias. While the COL2A1:COL1A1 ratio is recognised as a measure of cell differentiation, there is yet to be a study specifically examining this ratio in hypospadias. The aim of this study was to determine the COL2A1:COL1A1 ratio.

Background: Clear cell renal cell carcinoma (ccRCC) is the most common histologic type of RCC. However, the spatial and functional heterogeneity of immunosuppressive cells and the mechanisms by which their interactions promote immunosuppression in the ccRCC have not been thoroughly investigated.
Methods: To further investigate the cellular and regional heterogeneity of ccRCC, we analyzed single-cell and spatial transcriptome RNA sequencing data from four patients, which were obtained from samples from multiple regions, including the tumor core, tumor-normal interface, and distal normal tissue.
Spigelian hernia and cryptorchidism syndrome: open spigelian hernia repair and laparoscopic one-stage orchiopexy for ectopic testis.
BMJ Case Rep

Pediatric Surgical Services, Mary Bridge Children's Hospital and Health Center, Tacoma, Washington, USA
Spigelian hernia and cryptorchidism syndrome in children is increasingly reported in the literature. A variety of phenotypes have been reported, so diagnostic approaches and operative techniques remain poorly defined. The case of an infant male who presented with a left spigelian hernia and ipsilateral cryptorchidism who was initially misdiagnosed with an ectopic inguinal testis is presented.
