A 71-year-old man had pollakisuria, macrohematuria and sense of urinary retention. His urethrogram showed a giant bladder stone with a small urethral stone. ⋯ The giant bladder stone was removed. It weighed 310 g and is the 32nd reported in Japan.

We report a rare case of vasitis nodosa. A 54-year-old man was found to have a right spermatic cord mass during the herniorrhaphy operation. ⋯ Histological examination revealed disruption of the ductal lumen, granulomas with the sperm-like necrotic tissue and proliferation of the lymphocytes and plasma cells in the smooth muscle bundles. Pathological diagnosis was vasitis nodosa.

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.
