[A new method for transurethral prostatic commissurotomy].

Based on the principles of Shafik's prostatic commissurotomy, we have developed a new transurethral prostatic commissurotomy, which is characterized by cutting, layer by layer and section by section, the urethral mucosa, the bladder muscle layer and the prostate tissue within combined part of the urethra and prostate and by cutting the prostatic capsule with electrocoagulation. The comparison of clinical objective indexes has proved that the method is applicable to high risk patients with prostate hyperplasia and neck contracture leading to urethral obstruction after TURP.

[Segmental polar nephrectomy].

On the basis of anatomical studies of renal vessels, segmental polar nephrectomy has been designed. The key point is to identify blood-loss area of the segmental pole by interruption of the upper or the lower segmental polar artery before partial nephrectomy. The merits of the procedure are non-compression of the renal pedicle vessels, appropriate extent of the segmental polar nephrectomy and less hemorrhage.

A study of the renal sinus and its application in stone surgery.

The anatomical structure of the renal sinus was studied in 160 adult cadaver kidneys. Important anatomical features were described in the capsule of the sinus fatty tissue, including capsular septum of the hilus renalis, and the distribution of the posterior pelvic transverse artery. The implications of these findings in stone surgery are discussed.

Areas for safe percutaneous nephrocentesis--a study of practical anatomy.

The safest percutaneous nephrocentesis route is through the posterolateral aspect of the kidney. From study of 160 kidneys from adults at autopsy, we conclude that the most favorable nephrocentesis area is the lower major renal calyx and its minor calyces or the upper minor calyces. We believe that the lateral aspect of the middle calyces may be an area for safe nephrocentesis.
