Water-saving irrigation of paddy field to reduce nutrient runoff.

The purpose of this work is to study the effect of a type of water-saving irrigation (WSI) on nutrient runoff of paddy field. The volume of surface drainage was maintained low by WSI. In particular, WSI effectively reduced surface drainage in rain events.

[Ureteral-abdominal aortic fistula during the exchange of ureteral stenting: a case report].

We report a case of a patient with a fistula between the left ureter and abdominal aorta. The patient was a 44-year-old male who had undergone radiation therapy (intraoperative: 25 Gy, external beam: 50 Gy) and chemotherapy (CDDP: 250 mg) for retroperitoneal lymph node metastasis from seminoma. His postoperative course was complicated by stenosis of bilateral ureters, which were treated by indwelling double J-stents.

A rare case of penile metastasis of testicular cancer presented with priapism.

Priapism is thought as a condition of penile erection that persists beyond or is unrelated to sexual stimulation. Commonly two different entities of priapism are known, one is low-flow priapism and the other is high-flow priapism. It is important to distinguish these two conditions for the subsequent different treatments.

Surgical correction of buried penis after traffic accident - a case report.

Background: Buried penis, most commonly seen in children, is particularly debilitating in adults, resulting in inability to void while standing and it also affects vaginal penetration. We report a case of buried penis due to a traffic accident, which caused dislocation of the fractured pubic bone that shifted inside and pulled the penis by its suspensory ligament.

Case Presentation: A 55-year-old man was admitted to our hospital with a chief complaint of hidden penis while in the sitting position.

[Complete avulsion of ureter caused by abdominal blunt injury: a case report].

A 21-year-old woman who had been injured in a traffic accident appeared with abdominal pain and macroscopic hematuria. Computed tomography (CT) performed 6 hours after the injury showed extravasation of contrast medium in the right retroperitoneal space. Retrograde pyelography (RP) showed the interruption of right ureter at the site of ureteropelvic junction.

Prostate cancer detection by prostate-specific antigen-related parameters.

Total serum prostate-specific antigen (PSA) levels, free-to-total PSA ratio (F/T ratio) and PSA density (PSAD) were compared to clarify the clinical significance of these parameters in the diagnosis of prostate cancer (CaP) with intermediate PSA concentrations (4-10 ng/ml). PSAD and F/T ratio were obtained during the period from May 1999 to April 2001 from 43 patients with serum PSA concentrations of 4-10 ng/ml who underwent ultrasound-guided systematic sextant biopsies. PSAD was compared with total serum PSA and F/T ratio via receiver operating characteristic (ROC) curves for diagnosis of CaP.

Telomerase activity in renal cell carcinoma by modified telomeric repeat amplification protocol assay.

Background: Previous assessments by the conventional telomeric repeat amplification protocol have not been reliable for the quantitation of telomerase activity. We, therefore, determined telomerase activity in renal cell carcinoma (RCC) tissue by the modified sensitive telomeric repeat amplification protocol assay.

Methods: Telomerase activity was examined in 23 cases of RCC and in the adjacent normal kidney tissue, and assessed for associations with clinical and pathological variables of the disease.

[Ureter cancer of complete double renal pelvis and ureter: a case report].

A 66-year-old man presented at our hospital with left back pain. Intravenous pyelography, computerized tomography and magnetic resonance imaging revealed ureteral tumors of the complete left double renal pelvis and the ureter. An endoscopic examination disclosed a papillary tumor from the left ureteral orifice of the lower pole of the kidney.
