Iohexol in urography.

Thirty patients injected intravenously with a nonionic contrast medium, iohexol, for urography were compared with 30 patients similarly injected with sodium iothalamate. Comparable radiographic results were obtained in these patients with normal renal function. Few minor responses were observed with the iohexol, suggesting that it may prove to be an attractive contrast medium for this purpose.

Aspiration biopsies of chest lesions.

1223 patients underwent aspiration biopsy with a diagnostic yield of 86.4%; 24.2% of the patients had a small pneumothorax, but only 4.4% required treatment; one patient developed a moderate hemothorax. The method, problems, and complications including morbidity and mortality are discussed. The relative success of aspiration biopsy with different lesions of the lung and mediastinum is identified.

Retroperitoneal fibrosis and inapparent obstructive uropathy.

Emphasis is placed on the minor degree of caliectasis often observed in the presence of severe renal failure in patients with retroperitoneal fibrosis. This finding should suggest the diagnosis in individuals presenting with obscure causes of renal failure. A possible explanation for this is based upon an interference with ureteral dynamics and subsequent interference with normal ureteral peristatic activity rather than mechanical obstruction of the ureter per se. Twenty-one patients with retroperitoneal fibrosis are reported with the usual sex and age distribution (mostly male, aged 40-55 years). Two of the patients are interesting because of associated cardiac disease and 31 had been on prolonged methysergide therapy for migraine headaches. Eighteen patients appeared to be improved or cured and 3 died.

Complications of renal cyst exploration versus renal mass aspiration.

This report presents a comparison of the complications of surgical exploration with unroofing and renal cyst puncture. Two hundred fifty-five patients were operated on, with a mortality rate of 1 per cent and a morbidity rate of 28 per cent. The complications in 63 patients examined by mass aspiration included a morbidity rate of 6.4 per cent and no mortality. The possibilities of over-looking carcinomas through cyst aspiration are weighed against the demonstrated morbidity of surgical exploration and found to be much less significant. The authors recommend that an asymptomatic renal mass that radiographically appears to be a cyst and is unaccompanied by urine changes or clinical stigmata of renal neoplasia be treated by cyst aspiration and not subjected to surgical exploration.

A new technique for urethrography.

The male urethra can be demonstrated following intravenous urography by having the patient void against the partial obstruction produced by a penile clamp. The clamp is useful for both the normal or stenosed male urethra.
