Evaluate the frequency and assess curative and preventive measures against urinary lithiasis in patients treated with indinavir.Fourteen HIV seropositive patients who developed severe and acute flank pain were included. Four of the patients receiving 800 mg indinavir t.i.d. had fever (38.5 degrees C) or delayed secretion (2 h). Delay from indinavir treatment onset was 1 to 321 days. During the same period, 155 patients had been treated with indinavir. Clinical features, radiology and laboratory results were recorded in addition to an analysis of the lithiasis if possible.Transient moderate renal failure occurred in 8 patients. Mean urine pH was 6. Serum phosphorus, calcium, and uric acid, liver tests and urinalysis were normal. A JJ ureteral stent was inserted in 4 cases due to complications. In all cases, fluids, analgesics and antispasmodics provided favorable outcome. Inversely, nonsteroid antiinflammatory drugs given in 2 patients had a deleterious effect on renal function. The lithiasis was eliminated in 3 cases and infrared spectrophotometry demonstrated a structure compatible with indinavir monohydrate.The formation of urinary lithiasis is a frequent complication of indinavir therapy (9%). Hyperhydration and urine acidification are usually successful but emergency drainage is required in approximately 3% of cases. Nonsteroidal antiinflammatory drugs should be avoided due to the risk of renal toxicity. A precise evaluation of fluid intake and diet, drug associations and personal history is needed to recognize patients at risk of recurrent lithiasis formation.

Determine the incidence of prostate cancer in patients consulting for common miction disorders and serum prostatic specific antigen (PSA) between 4 and 10 ng/ml.A total of 153 patients consulted for miction disorders. In 107 of them, the digital examination was abnormal and PSA was between 4 and 10 ng/ml. Transrectal sonography and prostatic biopsies were performed in these 107 patients. We determined the number of cancers detected and assessed the contribution of PSA density (PSAD) to diagnosis. In patients undergoing radical prostatectomy, invasion of the capsule (C+) and positive exeresis section (M+) were recorded.Cancer of the prostate was diagnosed in 29.4% of the patients on the basis of at least 1 of the 6 biopsies. This rate was 47.8% in patients with an abnormal and 21.5% with a normal digital examination. Radical prostatectomy was performed in 32 patients: 50% of them were C+ and 33% M+.Biopsy of the prostate is indicated in patients with an abnormal prostate at digital examination when PSA is between 4 and 10 ng/ml. When the prostate appears to be normal, PSAD may be helpful in determining when to perform a biopsy. Intermediary serum PSA levels do not guarantee favorable pathological characteristics.

Manifestations of urological involvement, including tumour development, infection and impaired micturition are frequent in patients with acquired immunodeficiency syndrome. The frequency and consequences of dysuria itself are difficult to evaluate due to the concomitant effects of underlying infections, obstructive or neurological pathologies.Thirty-nine HIV-positive patients presenting impaired micturition including isolated dysuria, urine retention pollakiuria or urge incontinence were followed prospectively from February 1989 to September 1992. Each patient underwent a complete neurological and urological examination. Imaging included CT-scan or magnetic resonance imaging of the brain or spinal cord, echography of the bladder and prostate, intravenous pyelography or ascending and micturition urethrocystography as required. Urinary function tests were used to determine the cause and exact type of impairment to establish therapeutic protocols.A neurological origin was found in 61.5% of the cases. Cerebral toxoplasmosis and HIV encephalitis were the most commonly found causes. Symptomatic relief was obtained in most patients with bladder- sphincter active drugs. After a mean follow-up of 9 months (range 2-24 months), long-term improvement was achieved in 57.9%. Seventeen patients (44%) died within a delay of 2 to 24 months (mean 8 months) after onset of dysuria.Signs of impaired micturition are frequently encountered in HIV-infected patients. A full work-up is needed for diagnosis and treatment adaptation. Neurological disease is the most frequent underlying cause and would appear to be a sign of poor prognosis.
