Objective To evaluate the clinical application of superselective renal artery embolization in the treatment of iatrogenic renal hemorrhage. Methods The iatrogenic renal hemorrhage in fifteen patients was first demonstrated by renal arterigraphy to diagnose the rupture site and degree of injury. And then they were treated by percutaneous catheterized superselective renal arterial embolization through guidance of guide wire. Results In all 15 patients, the occlusive ruption of bleeding arteries and disappearance of extravasation staining were found after the superselective catheterized renal arterial embolization. Clinically, the bloody urine turned clear without macroscopic hematuria during 1-3 days in all patients after the procedure. Conclusions Superseclective renal arterial embolization treatment signified a less invasion, less complications, good hemostatic efficacy, and maximal preservation of renal tissue and function for iatrogenic renal hemorrhage. The treatment is worthy to be recommended.

Objective To study the efficacy and safety of transurethral plasmakinetic resection of prostate (PKRP) in treatment of benign prostate hyperplasia in elderly patients aged 80 years and over. Methods Retrospective clinical analysis of 180 case of high risk of benign prostate hyperplasia treated by PKRP in patients aged 80 years and over. Results All the 180 patients underwent the operation successfully. The average time for operation was (45.5±23.3) min and the resected prostate was in an average of (60.3±23.3) g. Neither of blood transfusion during the operation nor aductor reflex and transurethral resection syndrome occurred. International prostate symptom score,residual urine and quality of life decreased from (29.5±5.3) to (10.2±2.8),from (130.5±45.5) ml to (13.5±7.1)ml and from (7.2±1.1) to (1.0±0.5) respectively. The maximum flow rate elevated from (6.2±1.8) ml/s to (24.5±3.1) ml/s. The differences in the above indicators were statistically significant between pre- and post- operation (P＜0.05). Conclusions Transurethral plasmakinetic prostatectomy is a reliable and effective surgical method, especially for the aged patients with benign prostate hyperplasia.

Chronic treatment with Salvia Miltiorrhiza preventing left ventricular hypertrophy (LVH) and its possible mechanism--inhibiting the action of cardiac aldosterone in spontaneously hypertensive rats (SHR) were investigated. Normotensive Wistar-kyoto (WKY) rats and SHRs were used. Part of SHRs was treated with Salvia Miltiorrhiza for 12 weeks. Systolic blood pressure (SBP) and left ventricular mass index were measured. Sections of heart tissue were stained with HE method and VanGieson method. Collagen volume fraction was determined in the left ventricle by automatically quantitative morphometry. Cardiac aldosterone concentration was measured by radioimmunoassay. The results indicated that compared with WKY rats, SHRs exhibited higher SBP, left ventricular collagen volume fraction, and aldosterone concentration (all P < 0.05). After the treatment with Salvia Miltiorrhiza, SBP, left ventricular collagen volume fraction, and aldosterone concentration in SHR were decreased as compared with control group (P < 0.05) except SBP. It was concluded that chronic treatment with Salvia Miltiorrhiza could prevent left ventricular hypertrophy in SHR, significantly inhibit collagen compositions in left ventricle. The mechanism was probably related with the inhibition of the cardiac aldosterone action.
