Case Reports[Paravesical angiofollicular hyperplasia of the lymph nodes (so-called Castleman tumor). A contribution to differential diagnosis of benign retroperitoneal space-occupying lesions].
Clinical and pathological presentation of a benign so-called "Castleman Tumour", is very rare in the urological literature. It caused impression of the bladder and displacement of the right ureter in a 47-year-old male patient with a six-year case history. Detailed description of the two types of tumours is presented differing both histologically and clinically. This adds to the differential diagnosis in cases of space occupying lesions in the retroperitoneal cavity.

Case Reports[Risks of operative treatment of prostatic adenoma in terminal renal failure].
Three patients in terminal renal failure who developed strictures in the operative area after the operative removal of a prostate adenoma are presented. These typical complications, as described in the literature, are not only a result of transurethral resections. ⋯ Strictures are a result of an insufficient or lacking urinary flow in terminal renal failure. When sufficient quantity of fluid can be offered to the bladder for drainage through a suprapubic catheter strictures after transurethral and open prostate operations can be avoided.

[Blockade of the obturator nerve in transurethral electroresection of urinary bladder tumors].
Stimulation of obturator nerve during transurethral electroresection causes violent adductor muscle contraction, and is a major cause of inadvertent bladder perforation. General anesthesia with muscle relaxants is often required when the bladder tumor is in the area where the obturator nerve passes in close proximity to the inferolateral bladder wall. ⋯ We herein describe the technique and results of local obturator nerve blockade. Use of neutracer and pole needle makes the obturator nerve block a completely reliable, safe and easy procedure.

Case Reports[Subcapsular kidney hematoma: a rare complication of paravertebral infiltration].
Two patients developed subcapsular hematomas of the kidney following orthopaedic paravertebral injection. Clinical course and radiological findings are reported. Renal subcapsular hematomas are indeed frequent complications after stomach and lower thorax injuries; these are also known after diagnostic or therapeutic kidney-punctures. However, damage to the kidney by paravertebral injection is extremely unusual and not previously reported in the literature.

The historical development is described for the technique of transrectal aspiration biopsy of the prostate [23, 25] and for the cytological diagnosis of prostatic cancer [6, 12, 19]. The cytological criteria for the diagnosis of prostatic cancer and its different malignancy grades, its regression after therapy, other malignancies of the prostate and the various forms of prostatitis are described in detail. The validity of the histological and cytological diagnosis of the prostate are compared. ⋯ It is also possible to differentiate cytologically the various forms of prostatitis. Except for rare, exceptional cases, the cytological diagnosis of prostatic lesions is equivalent to the histological diagnosis, but requiring a skilled cytologist. Aspiration biopsy of the prostate is less risky and less uncomfortable for the patient than the punch biopsy.
