The authors report 45 cases of unilateral renal atrophy. The circumstances of discovery are related to the urological symptoms: pain, hematuria, pyuria. On the other hand, hypertension is rarely the reason for consultation. Women are more affected than men. Intravenous urography, retrograde cystography and arteriography are essential examinations to collect information concerning the etiology. Dynamic scintiscanning with measurement of the percentage of isotope fixed on the kidneys, has the advantage of permitting comparative evaluation of renal function on each side. In our study, obstruction of the urinary tract was more frequent than parenchymatous disease favoured by infection. Vascular abnormalities were rare. The etiological enquiry remained, however, negative in one third of cases. Surgical operation was necessary when a urological abnormality was the cause of persistence of severe symptoms. On the other hand, removal of the atrophic kidney does not seem to us advisable when decided simply to relieve hypertension. The latter point is particularly discussed.

The symptomatology and delay in diagnosis in a series of 502 germinal tumours of the testis were surveyed. Pain is much more commonly a feature than is usually appreciated and often leads to the condition being treated as inflammatory for much longer than it should be. Most surgical textbooks are not helpful in this regard. Delay in exploring the testis, and, particularly, delay in initiating follow-up therapy after orchidectomy, were associated with a higher stage of disease and poorer results, most clearly seen in nonseminomatous tumours. As the incidence of testicular tumours seems to be rising, a high index of suspicion in any abnormality of the testis in a post-pubertal male is advocated. Exploration through an inguinal incision for any mass or enlargement of the body of the testis not associated with dysuria and pyuria is essential. If a tumour is found, supplementary treatment must be given without delay. Judicious X-ray therapy, surgery and cytotoxic drugs can save most patients. Seminoma, in particular, can be cured, even in the advanced case.

From 11 personal case studies, the authors conduct a general review of the problems raised by Cowper's glands. Cowper's glands, accessory sexual glands, are made up of main glands situated behind and on either side of the bulbar urethra right at the level of the urolgenital diaphragm and of accessory glands situated in the thickness of the bulbar spongy body. The main glands are drained by long canals (several centimeters in length) which empty into the bulbar urethra by paramedian orifices. The fusion of these canals into one single canal at the urethral opening, although rare, could lead to obstruction. These canals can be the site of cystic dilatation ranging from a few millimeters to as much as 6 cm in diameter. These cysts are rarely due to terminal canal obstruction as the result of chronic inflammatory urethritis. Most often they are congenital. The cysts which develop at the level of the accessory glands are usually obstructive while those which develop at the level of the main glands rather have a perineal expansion. The indicative signs of this particular pathology are not specific (pyuria, hematuria, enureis, known urethral stenosis, dysuria with pollakuria, perineal pain with post voiding urethral dripping). Voiding urethrography investigation (the best) shows: --either cystic dilatation seen as a lacuna on the ventral aspect of the urethra, --or opacification of the dilated cavities of the exretory canals which have been spontaneously broken or opened by endoscopic manoeuvres. The opacification of these cavities leads often to the erroneous interpretation of "diverticula" of "incomplete duplication of the urethra" and yet their essential characteristic is twofold: they are oriented in an anterior-posterior direction with respect to the urethra and lead back and away from it; they have a canal type of morphology for at least part of their course.

The frequency of Staphylococcus saprophyticus, formerly Micrococcus subgroup 3, as the cause of bacteriuria is reported. Of 787 consecutive female outpatients with signs of bacteriuria, 173 (22.0%) yielded S. saprophyticus, predominantly in pure culture and in high counts. In the age group 16--25 years, this organism was demonstrated in no less than 42.3%. In hospitalized women and in men with signs of bacteriuria, on the other hand, S. saprophyticus was a rare finding (0.9% and 0.5%, respectively). The figures in female outpatients aged 15--30 years were similar over a three-year period, but higher during summer and fall as compared with those in winter and spring. The patients regularly had rather severe symptoms of acute urinary tract infections with dysuria and often loid pain. Hematuria and pyuria were common. All strains of S. saprophyticus had a fairly even and high susceptibility to antimicrobial agents except nalidixic acid. Recurrent infections were common. The origin of this infection is still obscure.

Treatment of infections by the use of antimicrobial agents should be made essentially in a dose close to the minimally required dose. Acute uncomplicated cystitis in female fits as the subject for a single-dose therapy since it is an infection reactive relatively easily to antimicrobial agents. Accordingly, an assessment has been made regarding the therapeutic results of the single-dose therapy in 76 female cases of acute uncomplicated cystitis by the use of LVFX 200 mg which is a new quinolone. The urinary concentration more than MIC90 to Escherichia coli is sustained for about 3 days by this single-dose therapy. As a result of judging the therapeutic results from the reactions of the three clinical findings of pain on micturition, pyuria and bacteriuria, excellent therapeutic results were obtained with effective rates being 100% (76/76) on the day 3, 93.9% (46/49) on the day 7 and 94.4% (34/36) on the day 14. The rate of cystitic symptoms which recurred posed no problem, being 12.5% (5/40) up to three months, as investigated by a questionnaire. As a result of performing close urological examinations such as cystoscopy on six cases with insufficient results or recurrence, we could detect mild underlying conditions which are considered to be intractable factors in the bladder in three cases. From the above results, the single-dose therapy of acute uncomplicated cystitis in the female by LVFX which is a new quinolone was considered to be an excellent therapeutic drug from its characteristics such as its therapeutic results being the same as the conventional therapy by daily administration, excellent drug compliance, low cost, hard selectiveness of resistant strains, less side effects and furthermore it gives the opportunity of detecting a latent and mild underlying condition.

Over a period of 33 months in a paediatric accident and emergency department, the clinical pattern and possible causes of vulvovaginitis were studied prospectively in 200 girls presenting with genital discharge, irritation, pain, or redness. The major causes were poor hygiene and threadworms. The suspicion of sexual abuse arose in a few girls but no organisms of sexually transmitted disease were found. Urinary symptoms were common but only 20 patients had a significant bacteriuria and 40 had sterile pyuria. Specific skin problems occurred in 28 cases. Simple measures to improve hygiene and treatment of threadworms gave effective relief. Genital irritation caused urinary symptoms with no clinical evidence of infection, and it is advised that antibiotic treatment should await urine culture. Specific skin problems require help from a dermatologist. The possibility of sexual abuse must be considered especially if the vulvovaginitis is persistent or recurrent after adequate treatment.

Urinary tract infections are among the most common bacterial infections. To provide appropriate and cost-effective treatment, physicians need to stratify patients with urinary complaints into uncomplicated or complicated categories. This can be accomplished by the history, presenting symptoms, risk factors, and physical examination. Complicated urinary tract infections occur in patients with a history of recurrent infections, signs or symptoms of upper tract disease, or coexisting conditions such as pregnancy, immunosuppression, or structural anomalies of the urinary tract. Uncomplicated urinary tract infections occur in otherwise healthy women who have a history of lower tract symptoms of short duration. Symptoms of urinary tract infection include some combination of dysuria, frequency, urgency, hematuria, and suprapubic pain. An uncomplicated urinary tract infection is not accompanied by fever or flank pain. The microbiology of uncomplicated urinary tract infection is predictable, with Escherichia coli and other Enterobacteriaceae, Staphylococcus saprophyticus, and Enterococcus causing more than 90% of urinary tract infections. A history, brief physical examination, and urinalysis are all that is necessary to diagnose a urinary tract infection. Some of the specialized dipsticks and rapid screens are as accurate as microscopic examination in detecting urine white cells. A presumptive diagnosis can be made when a patient has clinical symptoms and some combination of pyuria, hematuria, or bacteriuria. Urine cultures are unnecessary in uncomplicated urinary tract infections and add substantially to the cost of therapy. Pitfalls in the diagnosis include other entities causing dysuria, such as vaginitis, vulvar lesions, physical or chemical irritants, and sexually transmitted diseases. Appropriate therapy requires selection of a drug and determination of the length of treatment. A minor infection should be treated with easy, safe, cost-effective therapy. For urinary tract infections, there are too many antibiotic options, ranging from a single, parenteral dose to a 14-day course of oral medication. Early optimism about single-dose oral therapy has been replaced by evidence suggesting that 3 days of therapy is probably the best. This will eradicate simple urinary tract infections in virtually all patients and decrease the incidence of relapse, whereas patients who are treatment failures usually have occult upper tract infection. Drug choices for short-course therapy include representatives from the penicillin, sulfa, and quinolone families. Selection of a specific drug requires consideration of costs, allergies, side effects, and spectrum of activity. A knowledge of local microbial sensitivity profiles and individual patient tolerance is helpful in guiding the clinician to the appropriate therapeutic regimen.

A prospective study was made of 125 ureteric stones in order to detect factors which would predict the successful outcome of conservative treatment. The factors studied were the duration of pain prior to presentation, pyuria, haematuria, surface regularity of the stone and the degree of obstruction as seen radiologically. In stones less than or equal to 10 mm in size, conservative treatment was successful when the duration of pain was less than 30 days (39/45), when there was no significant pyuria (53/82), when the stones had an irregular surface (44/65) and when obstruction was only partial (55/88). Since most of these factors were interactive, further statistical analysis showed that duration of pain was the only significant factor in predicting the outcome of conservative treatment. In stones greater than 10 mm in size these factors had no predictive value and only 2/23 were passed spontaneously on conservative treatment.

During the past three and half years (Jan, 1984-Jun. 1987), 14 cases of ureteropelvic junction obstruction presented with abdominal pain were encountered in the Department of Pediatrics, Mackay Memorial Hospital. Eight cases were male and six female. Their ages ranged from 4 years old to 12 years old. The duration of abdominal pain lasted for several days in 5 cases, several months in 4, and several years in another 5 cases. The abdominal pain was usually recurrent. It occurred once every 2 to 6 months. The location of pain was predominantly in the left abdomen and the periumbilical area. Cramping was the most characteristic symptom. Besides abdominal pain, several cases also had vomiting or abdominal mass. Laboratory examination showed some cases to have microscopic hematuria and others pyuria. All were proved by renal ultrasonography to have varying degrees of hydronephrosis. Intravenous pyelography or retrograde pyelography also confirmed the diagnosis of ureteropelvic junction obstruction. In 9 of the 14 cases, surgical intervention was performed to correct abnormalities. Six cases were followed up regularly; all showed improvement, however, one developed ureteropelvic junction obstruction on the contralateral kidney one year later. The remaining five cases who did not receive surgical treatment continued to have recurrent abdominal pain.

In acute "primary" pyelonephritis (APP), kidney infection occurs despite normal urinary tract morphology. Typical features of APP are spiking fever and chills, loin pain, pyuria, bacteriuria, isolation of uropathogenic strains of E. coli, and specific renal CT scan images. APP may be atypical when lacking pain, or fever, or when urine cultures are negative, or when urinary bacteria do not exhibit characters of uropathogenicity, or when CT scan examination is negative. Such atypical features entail loss of time in diagnosis, and thereby delayed treatment and increased risk of cortical scar formation. However, they are virtually never observed simultaneously in a given patient.
