Retrocaval ureter and right ureteropelvic junction obstruction: a case report and literature review.

A clinical case involving a patient with retrocaval ureter and right ureteropelvic junction obstruction (UPJO) is presented, accompanied by a comprehensive review and discussion of relevant literature. The patient, a 43-year-old female, was admitted to the hospital after discovering right hydronephrosis 2 weeks prior. Computed tomographic urography (CTU) revealed significant right hydronephrosis, a retrocaval ureter, and compression of the right renal variant artery causing UPJO.

Artificial cavernosa-like tissue based on multibubble Matrigel and a human corpus cavernous fibroblast scaffold.

Ex vivo tissue culture of the human corpus cavernosum (CC) can be used to explore the tissue structural changes and complex signaling networks. At present, artificial CC-like tissues based on acellular or three-dimensional (3D)-printed scaffolds are used to solve the scarcity of primary penis tissue samples. However, inconvenience and high costs limit the wide application of such methods.

Effect of a Single Light-intensity Walking Session on Sleep Quality of Patients with Bladder Cancer: A Randomized Cross-Over Study.

Objectives: Exercise has been recommended to enhance sleep. However, there is a paucity of studies investigating the relationships between exercise and sleep problems in patients with bladder cancer. The authors explored the effects of a single bout of light-intensity walking on the sleep quality of patients with bladder cancer who have sleep disorders.

Clinical analysis of retroperitoneoscopic nephroureterectomy for renal tuberculosis.

Objectives: To explore the feasibility and safety of retroperitoneoscopic nephroureterectomy for kidney tuberculosis.

Methods: Forty-eight retroperitoneoscopic nephroureterectomies and thirty-five nephroureterectomies for kidney tuberculosis procedures were performed from June 2008 to December 2014. The patients consisted of 53 males and 30 females with a mean age of 36 years (range: 26-51 years).
