This study was designed to evaluate signs and stat tests as an indicator of lower urinary tract infection in female subjects with urogenital complaints at an out-patient clinic. Of various symptoms including hematuria, pollakiuria, dysuria, urinary retention, and micturition pain, pain during micturition was present in 48% of 25 patients with urinary tract infections and in 4% of 27 patients without urinary tract infections, and was the sign with the highest positive predictive value. Comparison and discrimination of the infection and non-infection groups using a single laboratory valuable yielded significant F-statistics for urinary leukocyte esterase (14.5) and leukocyte count in urinary sediment (31.1), and revealed large Mahalanobis' distances for the same variables. Multivariate analysis using a discriminant function of categorical data (Hayashi's Suryoka type 2) revealed that combining occult blood with leukocyte esterase in the urine or combining red cell count with leukocyte count in sediment did not yield substantially smaller misclassification error than did leukocyte esterase alone or leukocyte count alone. It was concluded that neither urinary occult blood nor red cell count in sediment contribute substantially to the prediction of urinary tract infection. For the purpose of detecting urinary tract infection among outpatients, a receiver-operating characteristic analysis demonstrated that the optimal cut-off point in sediment was 3 or more leukocytes per microscopic high power field (x 400). Urinary leukocyte esterase was found to have limitations for use in screening, because its optimal decision level is equivalent to trace esterase reading on the dipstick test.

Observations are presented on 9 patients recently treated in the University Teaching Hospital, Lusaka, Zambia, for painful urinary frequency, suprapubic pain and microscopic and/or macroscopic haematuria without any demonstrable urinary tract infection. At cystoscopy the bladder mucosa of all patients depicted a highly characteristic, uniformly congested appearance with no demonstrable ulcers; there was no significant reduction in bladder capacity. The histological appearance was essentially non-specific in type with an apparent resemblance to that of interstitial cystitis; mast cells were, however, absent in all specimens. An important feature common to all patients was an associated HIV infection; cytochemistry of the bladder tissue did not reveal an associated cytomegalovirus cystitis. No such case was observed in Zambia prior to the advent of HIV infection and the phenomenon was observed only in seropositive patients. It has been suggested that the virus is likely to be associated with the genesis of the bladder symptoms. The natural history of the disorder, its incidence among the seropositive individuals and its pathogenesis remain unclear.

During a routine follow-up visit, 428 victims of sexual abuse and their caretakers were asked about genitourinary complaints. Symptoms elicited included vaginal pain, increased urinary frequency, dysuria, and enuresis. A urinalysis was performed for all victims with symptoms, and those with positive or equivocal urinalysis results had a urine culture done. Urinalysis and urine culture were performed on a control group of 53 consecutive asymptomatic victims. Twenty percent (85/428) of the victims complained of one or more genitourinary symptoms. The most common symptom was vaginal pain (51%). Of the symptomatic victims, only 2 had a urinary tract infection. None of the 53 asymptomatic control victims had a urinary tract infection. There was no significant relationship between the presence of genitourinary symptoms and repetitive abuse, genital trauma, vaginal contact, or gender of the victim. However, patients younger than 6 years of age were more likely to have genitourinary symptoms than older patients. These findings indicate that urinary tract symptoms following sexual abuse are common but that urinary tract infection is quite uncommon. Our study does not support routine screening of children for urinary tract infection solely because they have been sexually abused.

Enuresis affects 5 to 10% of primary-school age children. Nocturnal enuresis, or bedwetting, is often familial and boys are mainly concerned; daytime micturitions are normal, without urine loss or urinary tract infection. Hygienic rules associated with desmopressin or, in some cases, tricyclic antidepressant agents, alarm procedures or psychotherapy, result in a 70% success rate after 1 year. Bladder instability consists of diurnal and nocturnal disturbances, mainly in girls with recurrent urinary tract infections; affected children experience pollakiuria, urine loss and voiding emergencies. Urodynamic assessment of daytime enuresis is of major interest, mainly when dysuria is present. The treatment of non complicated bladder instability needs reeducation, i.e. biofeedback and/or administration of oxybutynin chlorhydrate.

A case is reported of intravesical placement of a vaginal contraceptive suppository. 2 previously reported cases involving the same brand of suppository and treatment recommendations are reviewed. A 29-year-old woman inserted a contraceptive suppository 15 minutes prior to intercourse. Subsequently, she noticed transient, poorly localized burning that had not been present before she used the suppository. The woman had no history of urinary tract infection or similar symptoms. She awakened 4 hours later with intense urethral pain and inability to void. Catheterization was performed 1 hour later, yielding grossly bloody urine, following which she was able to urinate. Pelvic examination was normal, and an x-ray was negative for a foreign body. The patient complained of severe urgency, frequency, and terminal dysuria 3 days later at follow-up. Physical examination revealed a normally placed urethral meatus calibrated at 21 degrees Fahrenheit. Cystoscopic findings were remarkable for a pale, edematous trigone that stood in sharp contrast to an erythematous pancystitis in the remaining bladder mucosa. No foreign body was present. Capacity was 100 cc, above which marked pain was experienced. The urethral mucosa was inflamed. The patient was treated with trimethoprim-sulfamethoxazole and 50 mg prednisone orally, which was tapered to 10 mg/day. The symptoms persisted 6 days after the mishap with urinary frequency every 30 minutes. Urine culture was sterile. The patient was given 50 mg methylprednisolone sodium succinate in 50 cc sterile water intravesically for 1 hour along with antispasmodics. The patient was asymptomatic by day 14. The clinical findings resemble previously reported cases. The patient had no similar symptoms before or since this episode. Since the urine culture was sterile, and the patient was not taking antibiotics, there was no apparent reason for the severe cystitis. It is strongly believed that urethral insertion of the suppository was the etiology of the symptoms.

Acute urinary retention has many etiologies. In the pregnant patient, especially at the end of the first trimester, an incarcerated gravid uterus is a rare but possible cause. The patient discussed is a 30-year-old, gravida 4, para 2012, woman who was 14 weeks pregnant and who presented complaining of lower abdominal pain, urinary frequency, urgency, and nocturia. Based on the patient's symptoms, a diagnosis of a urinary tract infection was made, and antibiotic therapy was begun. Her symptoms failed to resolve, however, and she was referred for further evaluation, which eventually revealed an incarcerated gravid uterus. The patient was referred to an obstetrician who re-positioned her uterus without difficulty, and she subsequently had an uneventful pregnancy.

The anamnestic, clinical and urodynamic findings of 377 consecutively investigated women were evaluated. 86 (23%) patients showed bladder instability. The intensity of involuntary bladder contractions and the occurrence of incontinence in association with involuntary detrusor contractions influenced the clinical significance of unstable bladders. The maximum urethral closure pressure however had no influence on it. Urge incontinence was the most reliable symptom distinguishing those patients with bladder instability. Frequency of micturition, nocturia and nocturnal enuresis were less reliable in this respect. Urinary tract infections showed no correlation to bladder instability.

We studied the urological aspects of the tethered cord syndrome before and after untethering. Presenting urological symptoms include incontinence in 10 (38%), voiding difficulty in 8 (30%), stool soilage in 7 (27%), pollakiuria in 8 (30%) and urgency and symptomatic urinary tract infection in 9 patients (34%). All patients had presacral skin lesion. In all cases cystometric study was done preoperatively and postoperatively. In this study, we noted that the overall clinical symptomatology and urodynamic parameters improved in 67.0% and 49.0%, respectively. Although no patient became normal after surgery, we found better improvement in patients treated promptly by neurosurgical intervention.

The blinded study of CBUE (cytobacteriological urine examination) test strips was carried out in 100 patients (65 women, 35 men), mean age 85.52 +/- 6.28 years, admitted for a short stay in a geriatrics department. Urinary infection was present in 19% of the cases. Typical clinical signs (pollakiuria, dysuria, hematuria, burning upon voiding) were rare, less than 10%. General signs, such as deterioration of general status (65% of the cases) and loss of autonomy (53% of the cases), on the other hand, were predominant and their relatively unspecific nature required a reliable screening test for urinary infection. Good results of sensitivity (89.5%), specificity (98.7%), and the leukocytes/nitrites values, confirmed the validity of the urine test strip in hospitalized elderly patients. In addition, the negative predictive value of the combination leukocytes and nitrites (90.8%) would have prevented 71 samples from being sent to the laboratory for CBUE, resulting in an obvious financial savings.

A retrospective study was performed to determine the proportion of dogs with hyperadrenocorticism or diabetes mellitus or both that had urinary tract infection (UTI) and to describe clinical and laboratory findings. Dogs with these endocrine disorders were included if results of quantitative urine culture were available and dogs were not receiving antimicrobials. Dogs with positive urine cultures were considered to have UTI and dogs with negative urine cultures were used as controls. Information including history, clinical signs, physical examination findings, and results of laboratory tests and urine culture was extracted from all records. Findings in dogs with UTI were compared with control dogs. There were 101 dogs with hyperadrenocorticism or diabetes mellitus or both that met inclusion criteria; 42 (41.6%) had UTI and 59 (58.4%) did not. UTI was present in 46% of dogs with hyperadrenocorticism, 37% of dogs with diabetes mellitus, and 50% of dogs with both endocrine disorders. There was no association between endocrine group and occurrence of UTI. Escherichia coli was the most common bacteria isolated, and cultures from 29 dogs (69%) showed growth of this organism. Of dogs with UTI, <5% had stranguria, pollakiuria, or discolored urine, whereas 60% had pyuria and 69% had bacteriuria. We conclude that UTIs are common in dogs with hyperadrenocorticism, diabetes mellitus, or both diseases. Clinical signs of UTI, however, are uncommon and results of urinalysis may be normal. Therefore, it is appropriate to recommend urine culture as part of the evaluation of dogs with these endocrine disorders.
