Although many urodynamic techniques have been used to evaluate the function of the lower urinary tract, the principles of these measurements are only based on a relationship between flow rate and pressure. In addition to these measurements, the intravesical urine stream would provide useful information on urodynamics. We have experimentally attempted to visualize the urine stream in a bladder using transrectal ultrasound examination. ⋯ The velocity of urine stream was approximately 28.4 cm/sec in the body and increased to 116.6 cm/sec at the bladder neck. Thus, the urine stream was accelerated toward the urethra during voiding. Therefore, it seems that visualization of the urine stream offers a new parameter for evaluation of urodynamic studies.

We performed parathyroidectomy for renal osteodystrophy due to secondary hyperparathyroidism on 16 patients with chronic renal failure who were refractory to medical management; subtotal parathyroidectomy on one patient and total parathyroidectomy with autotransplantation on 15 patients. Postoperative clinical improvement, i.e., bone and/or joint pain, pruritus and radiographic signs of renal osteodystrophy, was marked. After the operation, serum calcium decreased rapidly and adequate calcium replacement therapy was necessary. ⋯ However, combination of US, computerized tomography and 99mTcO4(-)-201T1C1 scintigram can be recommended as a localizing diagnostic method for compensating the disadvantages of each method. Clinical results after parathyroidectomy for secondary hyperparathyroidism are considered to be good. However, long-term followup is mandatory for early detection of persistent hyperparathyroidism or hypoparathyroidism.

Two cases of traumatic testicular luxation are described. Patients were a 21 year-old man and a 19 year-old man who were involved in a traffic accident. ⋯ Surgical replacement of the testis, which was dislocated at the right inguinal region, was successfully carried out in both cases. These cases are the 57th and 58th cases of traumatic testicular luxation reported in the Japanese literature.

Review Case Reports
[A case of emphysematous pyelonephritis with disseminated intravascular coagulation].
A case of emphysematous pyelonephritis with disseminated intravascular coagulation (DIC) is presented. A 54-year-old woman was admitted to our hospital because of unclear consciousness and extremely high blood glucose level. ⋯ Right nephrectomy was performed after the improvement of the patient's condition by the echo-guided drainage of the right kidney and the treatment for infection, DM and DIC. We reviewed 71 cases of emphysematous pyelonephritis in the Japanese literature and the choice of treatment was discussed.

We report our experience with extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral and cystine stones, which are known to be difficult to treat by this method. First, in order to determine the effectiveness of the ureteral catheter in the destruction of ureteral stones, we compared the clinical results of 121 patients treated without the catheter and 141 patients inserted with the catheter. There was no significant difference in the success rate between the two groups regardless of stone size, which indicates that the use of the ureteral catheter had no effect on the outcome of treatment. ⋯ These findings suggest that ESWL treatment without the ureteral catheter may be effective for ureteral stones with a diameter of less than 1 cm and non-impacted stones with a diameter of 1 to 2 cm, while combination therapy with other methods such as TUL may be better for other stones. We also performed ESWL on 6 patients with renal stones and 2 patients with ureteral stones which were cystine stones. Renal stones required an average 4.1 treatment with an average of 1,875 shocks per treatment, and ureteral stones required 1.5 treatment with an average of 1,833 shocks.(ABSTRACT TRUNCATED AT 250 WORDS)
