These data do not support routine HBO in the treatment of Fournier's gangrene. There was a trend toward higher morbidity and mortality in the HBO group, suggesting that treatment may have been given to patients who were more ill.

Many urologists trained in recent years are comfortable performing PCNL. The type of training received influences treatment recommendations, and percutaneous access is most often obtained by/in conjunction with radiologists. This information may be useful in guiding residency training programs in the preparation of residents for the treatment of large renal stones.

One hundred patients who have had nephrostomies performed for obstructive uropathy in the presence of extensive carcinoma have been retrospectively analysed. Patients with prostatic and cervical carcinoma had a moderately good long-term survival and quality of life, but those with bladder carcinoma or other primary sites had poor results. Significant factors in the selection of patients for nephrostomy drainage in the presence of pelvic cancer are discussed.

Of 200 patients with pelvic fractures 32 (25 male and 7 female patients) had urological injury. Of these 32 patients 31 had pubic ramus or symphyseal fractures: 29 had gross hematuria and a urine specimen was not obtained in 2. Only 1 of 77 patients with microscopic hematuria had serious urological injury. We believe that excretory urography is not necessary in all cases of pelvic fracture, and that urethrography and cystography are indicated only in cases of gross hematuria or when other clinical signs indicate a high likelihood of bladder or urethral trauma.
