Ultrasonography in the differentiation of complicated and uncomplicated acute pyelonephritis.

Differentiation of uncomplicated pyelonephritis versus complicated pyelonephritis has always been problematic. No clear physical signs or symptoms are diagnostic. To study differences between the two, we retrospectively reviewed charts of patients admitted to Charity Hospital, New Orleans, with febrile urinary tract infections. Criteria for inclusion were pyuria, positive urinary culture, and signs or symptoms of pyelonephritis. All patients underwent renal ultrasonography (US) before other diagnostic tests. US identified a potential emergency (hydronephrosis or abscess) in 11 of 98 patients (11.2%). The only significant contributing factor was the presence of diabetes mellitus, which was present in five of 11 emergent conditions and eight of 73 of the remainder (P = 0.003). US is inexpensive, easily obtainable in the emergency room, and sensitive enough to screen patients with pyelonephritis for complications. However, we believe it is mandatory in diabetics, because of the high incidence of abnormalities in this population.

Renal involvement in visceral leishmaniasis.

In a prospective study of 50 patients with visceral leishmaniasis, laboratory abnormalities suggestive of renal involvement were not infrequent. Proteinuria and/or microscopic hematuria or pyuria were observed in 51% of such cases. Twenty-four hour urinary protein excretion was elevated in 57% of patients in all cases below 1g/24 hours. An abnormal acid-load test was demonstrated in 12 of 18 patients studied before therapy of the parasitic infection with N-methyl-glucamine. Of interest was the demonstration of tubulo-interstitial involvement in the renal histology of all seven patients studied; also, in five of seven patients there was a proliferative glomerulonephritis, usually mild, on histologic examination. In general, there was a tendency to subsidence of abnormal laboratory findings within one month after specific therapy. Renal involvement in visceral leishmaniasis was mild and seemed to revert with the cure of the leishmanial infection.

Acute focal bacterial nephritis.

Clinical and radiographic characteristics of 12 patients with acute focal bacterial nephritis (AFBN) are presented along with review of the literature. Most patients presented with symptoms of an inflammatory or infectious process. Fever and pyuria were the most frequently encountered clinical characteristics. Imaging modalities that were used to establish a definitive diagnosis of focal bacterial nephritis included ultrasound, computed tomography, and intravenous urography with nephrotomography. Ultrasound was found to be the most effective and least costly method of diagnosis. Misdiagnosis of AFBN as abscess or tumor, which it may stimulate, could lead to inappropriate surgical therapy.

Mesangiocapillary glomerulonephritis type II (dense-deposit disease): clinical features of progressive disease.

Twenty-seven patients presenting to the Royal Melbourne Hospital between 1968 and 1988 with mesangiocapillary glomerulonephritis type II with intramembranous dense deposits (dense-deposit disease, DDD) are analyzed. Patients were divided into two groups on the basis of whether renal function deteriorated (14 patients) or remained stable (13 patients). At presentation or during the course of the disease, heavy proteinuria, macroscopic hematuria, and high quantitative urinary red cell or white cell counts characterized patients with progressive disease. Patients with crescents on their initial renal biopsy or with large numbers of polymorphs in glomerular capillaries corresponding with sterile pyuria were more likely to have deterioration of renal function. The average time from onset of symptoms to development of end-stage renal disease was over 16 years. The patient's clinical course could not be anticipated by serum complement profiles, the presence of C3 nephritic factor, or partial lipodystrophy. Pregnancy did not affect the course of the disease. Six patients underwent renal transplantation and the disease recurred on renal biopsy in four. However, only two individuals lost renal allografts due to recurrent DDD.

Vesicoureteral reflux detected among patients with nocturnal enuresis.

OBJECTIVES: To clarify the characteristics of vesicoureteral reflux detected in patients with nocturnal enuresis. METHODS: Voiding cystourethrography (VCUG) was applied in 1,088 patients who visited our outpatient clinic with the chief complaint of nocturnal enuresis. The clinical features of reflux were evaluated and the prognosis of reflux and nocturnal enuresis was analyzed. RESULTS: Reflux was detected in 86 ureters in 70 patients (6.4%) out of the 1,088 patients. The grade of reflux was 3 or less in all cases. The incidence of pyuria was 5 (7%) and that of renal scar during first examination was 1 (1%). The incidence of unstable bladder was 30 (75%) in 40 patients. The resolution rate of reflux in the cases which were followed-up for 2 years or more by conservative treatment was 50-66% for each grade of reflux. The percentage of patients who had siblings with a positive history of nocturnal enuresis and the incidence of frequency differed significantly between the enuretics with reflux and the 507 enuretics without urological abnormalities. CONCLUSIONS: Our data suggest that the incidence of reflux in patients with nocturnal enuresis was rather low in comparison with the past literature, the severity was mild and the resolution rate by conservative treatment was rather high.

Evaluation of the Coral UTI Screen system for rapid automated screening of significant bacteriuria in a regional centralized laboratory.

An evaluation of the Coral UTI screen system (Coral Biotechnology, San Diego, CA) compared to urinalysis/urine culture was done to assess its performance for rapidly screening a high volume of urine samples for significant bacteriuria in a regional central microbiology laboratory. A total of 1094 urine samples from ambulatory patients were evaluated. 670 (61.2%) urine samples were negative or positive [178 (16.3%)] by both methods. 217 (19.8%) other samples were UTI screen positive but had either no growth or no uropathogens on culture; 9 of these samples were possibly false negative by culture because of the presence of pyuria, indicating the presence of either a urinary tract infection or another inflammatory process. Another 29 (2.7%) samples had false negative screens because the urine culture was positive, but only 5 of these patients were treated with antibiotics after urine specimen collection. Overall, the Coral UTI screen has a sensitivity of 86.0%, a specificity of 75.5% and a positive and negative predictive value of 45.0% and 95.9% respectively. Routine use of the UTI screen would allow same day reporting of 65% of all urine culture results without having to proceed to culture.

Fever in the clinical diagnosis of acute pyelonephritis.

Acute pyelonephritis is a clinical syndrome that can be confused with other conditions. To investigate this problem, a retrospective cohort study was conducted using two mutually exclusive sets of clinical criteria for acute pyelonephritis in women 15 years of age or older who presented to the emergency department of a university hospital. All patients had pyuria, and one group had documented fever (temperature of > or = 37.8 degrees C) while the other group had a temperature of < 37.8 degrees C but had other evidence of possible upper tract infection. The study cohort was comprised of 103 febrile and 201 afebrile patients. Afebrile hospitalized patients were ultimately found to have another diagnosis more often than were the febrile hospitalized patients (35% v 7%; P = .02), and the afebrile nonhospitalized patients were more likely to have another diagnosis than were the febrile nonhospitalized patients (13% v 0%; P = .004). Other diagnoses included cholecystitis, pelvic inflammatory disease, and diverticulitis. The positive predictive value of the definition of pyelonephritis in the febrile group was 0.98, and it was 0.84 for the afebrile group. Physicians examining patients with clinical evidence of acute pyelonephritis but without objective fever should be alert for alternative diagnoses.

Clinical features of tiaprofenic acid (surgam) associated cystitis and a study of risk factors for its development.

A case-control study was performed to describe the clinical course and identify risk factors predisposing to the development of tiaprofenic acid associated cystitis. Cases were identified from reports to the Australian Adverse Drug Reactions Advisory Committee and a two-year (1995-1996) national surveillance programme. Definition of a case was onset of symptoms of cystitis while taking tiaprofenic acid with pyuria (>10 WBC/microl) and/or hematuria (>10 RBC/microl), and no evidence of urinary tract infection. Definitions of "prescriber-matched" and "unmatched" controls were those who had been prescribed tiaprofenic acid by the same prescriber within 12 months of the case without developing cystitis or were identified from the databases of local pharmacies of the cases respectively. 81 of 109 identified cases and 109 of 184 potential controls completed a standardised interviewer-administered questionnaire. Median time between the commencement of tiaprofenic acid and symptom onset was 6. 3 months (range 0.1-47.1 months). Median interval between presentation to doctor and drug cessation was 3.0 months (range 0-24. 5 months). In half the patients, symptoms resolved within 14 days of ceasing therapy. Increasing age was a risk factor for the development of tiaprofenic-acid associated cystitis, age >70 years-odds ratio 3.2 (95% confidence interval 1.3-7.9) compared with age <55 years. Patients taking aspirin had a reduced risk (odds ratio 0.3, 95% confidence interval 0.1-0.9). Dose and amount of fluid consumed per day were not related to the risk of cystitis. Earlier recognition of tiaprofenic acid associated cystitis can potentially reduce the morbidity related to this condition. Apart from an increased risk among older patients, it is likely that this condition represents a drug reaction that cannot be predicted from clinical variables.

Treatment of lower urinary tract infection in pregnancy.

Urinary tract infection (UTI) is a common complication of pregnancy. Approximately 20--40% of women with asymptomatic bacteriuria will develop pyelonephritis during pregnancy. All pregnant women, therefore, should have their urine cultured at their first visit to the clinic. In a clinical study comparing single-dose treatment with 3 g fosfomycin trometamol versus a 3-day course of 400 mg ceftibuten orally, the inclusion criteria were acute symptomatic lower UTI (acute cystitis), significant bacteriuria (> or =10(3) CFU/ml), pyuria and confirmed pregnancy. Excluded were patients with asymptomatic bacteriuria or acute pyelonephritis. Predisposing factors comprised a history of recurrent UTI, diabetes mellitus, analgesic nephropathy, hyperuricaemia or Fanconi's syndrome. Escherichia coli was the most frequently isolated pathogen in both groups. Therapeutic success (clinical cure and bacteriological eradication of uropathogens) was achieved in 95.2% of the patients treated with fosfomycin-trometamol versus 90.0% of those treated with ceftibuten (P, non-significant). The treatment of acute cystitis in pregnant women using a single-dose of fosfomycin trometamol was equally effective as the 3-day course of oral ceftibuten. Both regimens were well tolerated with only minor adverse effects. Long-term chemoprophylaxis should be suggested in patients with recurrent UTI or following acute pyelonephritis during pregnancy.

[Urogenital tuberculosis in children].

BACKGROUND: Tuberculosis of the uro-genital tract is uncommon in both sexes before puberty. CASE REPORTS: Case 1. A 10 year-old boy suffered from chronic cystitis. Urine examination showed pyuria without bacteria and absence of mycobacterium tuberculosis on direct smears and culture. Intravenous pyelography showed left ureterohydronephrosis and a non functioning right kidney with calcifications. A right nephrectomy was performed which showed caseous lesions with granulomas. A triple specific therapy failed to completely cure the vesicoureteral lesions. Case 2. A 9 year-old boy was admitted for the suspicion of appendicitis. Renal ultrasonography showed features of abscesses located to the right kidney and the liver. Laparotomy showed their tuberculous origin which was confirmed by histological examination and positive search for Mycobacterium tuberculosis in urine. The course was favorable under specific treatment. CONCLUSIONS: Diagnosis of tuberculosis of the uro-genital tract may be difficult leading to a delayed treatment and sequellae.

Current indications for transurethral resection of the prostate and associated complications.

Transurethral resection of the prostate (TURP) is the most common surgical procedure for relieving symptoms of benign prostatic hyperplasia. Here, we report our experience of current indications for TURP and their associated outcomes at Kaohsiung Medical University Hospital (KMUH). A total of 111 patients who underwent TURP at KMUH between May 2000 and December 2001 were included in this retrospective review. For each patient, the surgical indication was categorized into acute urinary retention, chronic complications (including renal impairment, recurrent urinary infection, bladder stone/diverticulum, post-void residue, and recurrent hematuria), and symptomatic prostatism. Thirty-five patients (31%) had acute urinary retention, 28 (27%) had chronic complications, and 48 (42%) had symptomatic prostatism. Most patients chose TURP only when medical treatment had failed to relieve symptoms, no matter what category they belonged to. Patients with acute urinary retention and chronic complications had larger prostates (p = 0.002) and more tissue resected (p = 0.05) than those with symptomatic prostatism. Patients with acute urinary retention seemed to be at greater risk of postoperative complications such as recurrent urinary retention and urinary tract infection. We suggest that urodynamic study may be necessary to rule out concomitant bladder dysfunction before surgery and that adequate prophylactic antibiotic treatment be used to decrease the risk of urinary tract infection during or after TURP, especially when pyuria is noted preoperatively in patients with acute urinary retention.

Pan-urethral wart treated with 5-fluorouracil intraurethral instillation.

We evaluated whether or not intraurethral instillation of 5-fluorouracil (5-FU) solution can rapidly, safely, and effectively eradicate intraurethral condyloma acuminata in a human immunodeficiency virus (HIV) carrier. A 43-year-old man presented with the major complaint of difficult micturition and blood dribbling from the urethral meatus for more than 6 months. He was an HIV carrier for more than 10 years and had undergone diathermy for perianal warts. Physical examination showed cauliflower lesions over the orifice of the urethra and frenulum base of the penile prepuce. Urinalysis disclosed pyuria and microscopic hematuria. Cystourethroscopy on the following day showed extensive wart lesions extending from the urethra to the bladder neck. Biopsy of the lesions was compatible with condyloma acuminata. 5-FU solution (500 mg in normal saline 50 mL) urethral instillation with massage at the ventral side of the penile shaft for 20 minutes was given once a week for 7 doses. The urine routine was normal. Management was then prescribed once a month until the lesions became invisible under urethroscopy. After 18 doses of 5-FU solution urethral instillation, no visible wart lesions were noted. He has been asymptomatic with no voiding difficulty for more than 1 year.

Pediatric urolithiasis in Kuwait.

In this retrospective study, 31 Kuwaiti children with renal stones were reviewed between January 1996 and September 2000. Male to Female ratio was 2.1:1 with a mean age at presentation of 38 months. Family history of renal stones was reported in 58%. Stones were localized to the kidneys in 74.1%, to ureters in 6% and to the bladder in 9.6%. Bilateral stones were found in 64.5%. Clinical manifestations included: hematuria in 70.9%, passage of stones in 64.5%, abdominal pain in 41.9%, urinary tract infections in 29%, sterile pyuria in 22.9% and urine retention in 16%. Causes of stone formation included hypercalciuria in 38.7%, hyperoxaluria in 19.3%, cystinuria in 12.9%, xanthinuria in 12.9%, urinary tract infection in 3.2%, obstruction in 9.6% and idiopathic in 3.2%. In conclusion, lithogenic metabolic causes were found to be the major predisposing factors to stone formation among Kuwaiti children whereas diet and environmental factors played a trivial role.

Oliguric acute renal failure in mycosis fungoides with lymphomatous infiltrates in the kidneys.

OBJECTIVE: To present the clinical picture of acute renal failure in patients with mycosis fungoides (MF) and renal lymphomatous infiltrates. To analyze the pathogenesis of renal failure. METHODS: Correlation of clinical picture, urinary findings, imaging reports and autopsy findings in two patients with long-standing MF who died with renal failure. CASE SUMMARIES: Both subjects had sustained oliguria in the last 2 weeks. One patient had persistent hypotension, normal urinalysis, normal renal sonogram, and scarce interstitial lymphomatous infiltrates with preservation of renal parenchymal architecture. He was thought to have ischemic acute renal failure not directly linked to the lymphomatous infiltrates. The second patient developed hypertension one month prior to death, and had moderate proteinuria, hematuria, pyuria, grossly enlarged kidneys with hypoechoic masses, and extensive replacement of the renal parenchyma by lymphomatous infiltrates. This picture is typical of renal failure secondary to lymphomatous replacement of the kidneys. CONCLUSIONS: The development of oliguric renal failure in MF with renal lymphomatous infiltrates may have varying clinical and imaging manifestations and pathogeneses. Potentially reversible pathogenic mechanisms should be systematically investigated, particularly if the overall clinical picture is not characteristic of renal failure secondary to lymphomatous replacement of the parenchyma.

Urine cytology in patients with urinary tract calculosis.

Urinary cytological examination was performed on 375 patients suffering from urolithiasis at the Department of Urology. University School of Medical Sciences, Bydgoszcz between 01.01.1991 and 31.12.1992. 189 were female (mean age: 47.5 years), 186 were male (mean age: 53.5 years). We found dysplastic cells in urinary sediments in 25.3% of patients before therapy and in 5.3% of patients after conservative or traditional operation and interventional therapy (ESWL. PCNL). Degenerated cells were found in 72% of patients before therapy and in 30.4% after therapy only. In our group neoplasmatical cells were not found. Inflammatory background was found in 44.5% before and in 21.9% after therapy, pyuria in 19.7% and 0.8% respectively. In urinary sediments we found concrements in 24% of patients before and 7.7% after therapy. However, 20 (51.3%) of 39 patients after interventional therapy (ESWL, PCNL) had concrements in urinary sediments. In conclusion, no abnormality was seen in 85.1% before therapy and in 31.2% after therapy. The significance of cytological examination in management of calculous diseases was discussed.

Eradication of urinary tract infection following spinal cord injury.

A prospective study to evaluate the microbiological efficacy of antimicrobial treatment for urinary tract infection (UTI) was performed in 64 catheter-free spinal cord injured (SCI) patients who were visited monthly by a public health nurse who collected urine for culture and urinalysis. Patients also mailed urine dip slides for weekly bacterial counts. UTI was defined as a culture yielding > or = 100,000 colonies/ml. Treatment was given to asymptomatic patients only if pyuria (> or = 10 urinary leukocytes/high powered microscopic field) was present. Initial treatment was for 7-14 days (group 1). When it became apparent during the study that eradication was difficult and relapse or reinfection frequently occurred within a short time after cessation of antibiotic, a second treatment course of > or = 28 days (group 2) was given. By the end of the study, in which all patients were followed for a minimum of 30 days post treatment, 39/42 (93%) cases in group 1 and 11/13 (85%) in group 2 who had initial eradication, had relapsed or become reinfected. The median number of days and standard error for group 1 to relapse or become reinfected was 16 +/- 2.5, and for group 2 it was 27 +/- 6. Development of drug resistance was documented when bacteria isolated prior to any treatment were compared with strains isolated after > or = 28 days of antibiotics. In this study, urine sterility was achieved in a minority of treated UTIs and was relatively short lived.(ABSTRACT TRUNCATED AT 250 WORDS)

Urologic status of 74 spinal cord injury patients from the 1976 Tangshan earthquake, and managed for over 20 years using the Credé maneuver.

OBJECTIVE: To evaluate the urologic safety of long-term Credé maneuver as bladder management in spinal cord injured patients. METHODS: Seventy-four paraplegics were included in this cross-sectional study. They were injured in the Tangshan earthquake in 1976. All patients have large volume (flaccid) bladders and have practiced the Credé maneuver for more than 20 years to expel urine. Current residual urine volume and urologic complications were investigated. RESULTS: 93.2% of patients have residual urine larger than 100 ml and 50% of cases larger than 300 ml. The prevalence of urologic complications is high: pyuria in 82.4%, urinary lithiasis in 31.3%, ureteral dilatation in 59.5%, hydronephrosis in 35.1% and renal damage in 16.2%. Men are more susceptible to upper urinary tract deterioration than women (P<0.05). CONCLUSION: The Credé maneuver is not safe for long-term use in spinal cord injury patients, especially in men.

Combined effect of clarithromycin and imipenem/cilastatin against urinary biofilm infection after pyeloplasty.

The present report concerns a 38-year-old man, who had been treated with pyeloplasty and lithotomy for the improvement of urinary excretion and resolution of a kidney stone. The patient developed a biofilm infection involving Pseudomonas aeruginosa and Staphylococcus epidermidis, and had been suffering from recurrent acute pyelonephritis for one year. Combination therapy with clarithromycin (CAM) and imipenem/cilastatin (IMP/CS) consisted of administration of CAM at a dose of 400 mg/day for 1 week, followed by 500 mg/day of IMP by intravenous infusion combined with CAM (400 mg/day) for 5 days. This therapy produced an immediate antimicrobial effect and no further signs of pyuria have been seen during one year of follow-up in this patient.
