Real-world outcomes of patients with renal cell carcinoma, surgically treated at regional hospitals, based on a prospective long-term survey of the pre-robotic era.

Purpose: Renal cancer surgery is frequently performed in small regional hospitals in Japan. This study evaluated the outcomes of renal cancer surgery, comparing results from the pre-robotic surgery era with those obtained with robotic surgery.

Methods: This prospective cohort study was conducted on patients who underwent renal cancer surgery between 2008 and 2013 at 14 hospitals, comprising 13 regional hospitals and a university hospital, registered in the Tohoku Urological Evidence-Based Medicine Study Group.

[TYPICAL TYPE CYSTITIS GLANDULARIS PRESENTING URINARY RETENTION IN A YOUNG MAN: ADJUVANT THERAPY USING ORAL CYCLOOXYGENASE-2 INHIBITOR: A CASE REPORT].

A 31-year-old man was referred to our hospital with urinary retention. Cystoscopy revealed multiple edematous papillary tumors on the bladder trigone and neck, which were removed by transurethral resection. The pathological diagnosis was typical type cystitis glandularis.

[ISOLATED METASTASIS OF RENAL CELL CARCINOMA TO THE LARYNX: A CASE REPORT].

A 55-year-old man underwent right radical nephrectomy after the diagnosis of right renal cell carcinoma (RCC). He did not show any relapse or metastasis for 3 years and 5 months after surgery. He was admitted to the hospital in April 2014 with a throat discomfort.

Efficacy of early ureteral ligation on prevention of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma: a prospective single-arm multicenter clinical trial.

Objective: The rate of intravesical recurrence after radical nephroureterectomy for upper urinary tract urothelial carcinoma is high. Seeding upper urinary tract urothelial carcinoma cells onto the damaged bladder wall is considered to be one of the causes of intravesical recurrence after radical nephroureterectomy. We evaluated the utility of early ureteral ligation in preventing the intravesical recurrence.

Analysis of Thermally Denatured Depth in Laser Vaporization for Benign Prostatic Hyperplasia using a Simulation of Light Propagation and Heat Transfer (secondary publication).

Laser vaporization of the prostate is expected as a less invasive treatment for benign prostatic hyperplasia (BPH), via the photothermal effect. In order to develop safer and more effective laser vaporization of the prostate, it is essential to set optimal irradiation parameters based on quantitative evaluation of temperature distribution and thermally denatured depth in prostate tissue. A simulation model was therefore devised with light propagation and heat transfer calculation, and the vaporized and thermally denatured depths were estimated by the simulation model.
