1/8. Pyocystis: two case reports of patients in renal failure.Two cases of pyocystis in patients in end-stage renal disease are reported. Pyocystis is a recognized complication of urinary diversion procedures, but also occurs in anuric or oliguric hemodialysis patients. The treatment differs from ordinary cystitis, requiring catheterization, bladder irrigation, and intravesical antibiotic instillation. When undiagnosed, pyocystis may progress to sepsis and death.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
2/8. Persistent flank pain, low-grade fever, and malaise in a woman treated with indinavir.This case report describes a 32-year-old woman treated with indinavir who developed mild to moderate flank pain, malaise, and low-grade fever. Sterile pyuria preceded increased serum creatinine levels. Workup revealed persistent pyuria, normal-sized kidneys, a normal intravenous pyelography, and negative urinary cultures. Renal biopsy showed interstitial nephritis and chronic inflammation. Collecting ducts contained crystals. Two months after treatment with indinavir was discontinued, serum creatinine levels returned to normal and pyuria disappeared. Sterile pyuria in patients taking indinavir may help to identify patients at risk for renal dysfunction and interstitial nephritis. Markedly increasing the fluid intake above the recommended dosage may ameliorate or even reverse the process of tubulointerstitial disease.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
3/8. Staghorn calculus presenting as sterile pyuria.urinary tract calculi are relatively common and usually symptomatic. We describe a patient who had several very unusual features with regard to his urinary tract calculus disease.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
4/8. methamphetamine abuse presenting as dysuria following urethral insertion of tablets.foreign bodies are inserted into the male urogenital tract for a variety of motives, and patients may present with symptoms of dysuria, urinary retention, hematuria, discharge, or priapism. Concomitant psychopathology is seen frequently, necessitating a thorough psychiatric assessment with attention to other acts of self-mutilation, suicide attempts, psychosis, or substance abuse. We report the case of an abuser of methamphetamine who inserted a sustained-release form of medication into his urethra, with resulting mechanical and pharmacological trauma.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
5/8. Elevated prostate-specific antigen: a case report and analysis.Prostate cancer is a frequent concern of the clinician caring for older male patients. The certainty of arriving at the correct diagnosis is related to the presenting patient's risk for prostate cancer, the results of the digital rectal examination, and the value of the serum prostate-specific antigen (PSA). A case report of a patient with acute urinary retention and an elevated PSA is presented. Possible explanations for the elevated PSA are discussed. The clinician's intuitive thought process is compared with an analytic approach using calculated probabilities. Several factors that complicate the estimation of the likelihood of prostate cancer are discussed.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
6/8. Sterile pyuria: consider chlamydial infection.We report the cases of two men referred to a genitourinary medicine clinic with sterile pyuria and subsequently found to have their urethras infected with chlamydia trachomatis. Chlamydial infection should be considered in the differential diagnosis of sterile pyuria, particularly in young, sexually active males. We discuss the consequences of inadequate treatment of the index case.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
7/8. Abnormalities of urinary sediment and renal failure following sulfinpyrazone therapy.A patient with recurrent thrompophlebitis had sterile pyuria with white blood cell casts and transient, mild renal failure during therapy with sulfinpyrazone. These abnormalities resolved on cessation of therapy, but similar changes in the urinary sediment recurred during therapy with sulfinpyrazone. These abnormalities resolved on cessation of therapy, but similar changes in the urinary sediment recurred during a second course of sulfinpyrazone therapy.- - - - - - - - - - ranking = 6keywords = urinary (Clic here for more details about this article) |
8/8. indinavir nephropathy in an AIDS patient with renal insufficiency and pyuria.indinavir has been described to cause crystalluria and nephrolithiasis in a variable number of treated patients. Acute renal failure, often reversible with discontinuation of the medication, induction of a diuresis and correction of urinary obstruction if present, occurs in a smaller percent of patients. One recent report described renal biopsy findings, indinavir crystals within cellular casts in the collecting tubules, in a patient receiving this antiretroviral agent. We report a second case of a patient with mild renal insufficiency and pyuria following indinavir therapy and describe similar renal biopsy findings.- - - - - - - - - - ranking = 1keywords = urinary (Clic here for more details about this article) |
