C-AMOX, a new prolonged acting preparation of amoxicillin was administered to 122 cases by oral administration of daily dosage 500 mg twice. Clinical effectiveness of C-AMOX was evaluated in 115 out of 122 cases (acute simple cystitis 87 cases, acute pyelonephritis 6 cases, complicated urinary tract infection 19 cases and others 3 cases), and the following results were obtained. 1. The clinical effect for 87 cases of acute simple cystitis was excellent in 54 cases (62%), moderate in 24 cases (27.6%) and poor 9 cases (10.3%), overall effective rate being 89.7%. 2. The clinical effect for 19 cases of complicated urinary tract infection was excellent in 6 cases (31.6%), good 8 cases (42.1%) and poor 5 cases (26.3%), overall effective rate being 73.7%. 3. Adverse reaction occurred in 2 patients, one gastric discomfort and the other one slight diarrhoea. No laboratory abnormalities attributable to C-AMOX were observed in the present study.

Presentation of the first exclusively retroperitoneal laparoscopic nephrectomy performed on a female patient diagnosed with chronic pyelonephritis in the right kidney who referred frequent discomfort in the ipsilateral lumbar fossa as well as sporadic urinary infections. The entire procedure was performed without entering the peritoneal cavity, creating a space in the retroperitoneum, using for that hydrostatic dilation following Gaur's recommendations and introducing in that space a total of 4 trocars. Surgery lasted 3 hours an 35 minutes, with a post-operative stay of 3 days; the anaesthetics used after surgery was minimum and patient's return to her usual daily activities was almost immediate after discharge. Considering our group's previous experience in laparoscopic nephrectomies, both in humans (another 3 cases) and experimental surgery (18 pigs), we believe retroperitoneal approach is a huge step ahead in urological laparoscopic surgery, since this is the typical approach in our specialty and allows a closer contact with the condition being treated. On the other hand, the combined retro- and transperitoneal accesses will involve-are already involving-a greater variety of laparoscopic techniques in urology.

We evaluated the pathogenic role of Corynebacterium urealyticum in the development of encrusted pyelitis (EP) and encrusted cystitis (EC), and their clinical consequences in renal transplant recipients. During a 4-year period, we studied seven renal transplant recipients with EP and two with EC. The records of 320 other renal transplant patients studied during the same period were used as a control group. C urealyticum (> or = 10(5) CFU/ml) was isolated from 4 patients with EP (urine 3, blood 1) and from 1 patient with EC (urine). Alkaline urines with struvite crystals, microscopic hematuria, and sterile conventional urine cultures were present in all our cases. All the patients with EP developed obstructive uropathy with deterioration of the renal function and pyelonephritis (4 patients) or renal abscesses (3 patients). Chronic urinary discomfort and macroscopic hematuria were present in the 2 patients with EC. Long-term vesical and ureteral catheterization were considered the most important risk factors for the development of EC and EP, respectively. Vancomycin was successfully used in 5 cases, but all the patients required a derivative procedure or a surgical resection of the incrustations to improve. We conclude that EP and EC should be investigated in renal transplant patients who develop pyelonephritis, obstructive uropathy, or chronic urinary symptoms. EP and EC could lead to the loss of their grafts. C urealyticum appears to have a pathogenic role in these entities.

Infections in pregnancy may complicate its course and harm the fetus or newborn after vertical transmission. Treatment of asymptomatic bacteriuria is mandatory in pregnant women given the high risk of secondary pyelonephritis. Intraamniotic infection usually arises by the ascending route and is associated with premature rupture of membranes. Vaginal infections promote preterm labour or premature rupture of membranes and may be transmitted to the child during labour. They must therefore be treated although they often cause little discomfort to the pregnant woman. Systemic infections due to viral, protozoal and bacterial pathogens may be transmitted transplacentally and cause embryopathies, fetopathies or neonatal infections. Depending on the responsible agent the negative impact on the course of pregnancy and on the fetus' or neonate's health can be prevented or reduced by prophylactic or therapeutic interventions.

Vesicoureteral reflux (VUR) is a risk factor for acute pyelonephritis, which can result in renal scarring (reflux nephropathy), hypertension, end-stage renal disease (ESRD) and complications during pregnancy, In deciding whether to recommend surgical correction of VUR, factors that should be considered include the previous and potential future morbidity of VUR in that individual, the risk of uncorrected VUR, the likelihood of spontaneous resolution or significant reduction in VUR, the efficacy and complications of medical therapy, the morbidity and discomfort associated with serial screening for VUR, the benefits and risks of surgical therapy, and economic factors. Currently, surgical correction is recommended for those who fail medical therapy, or if the child has grade V VUR, bilateral grade IV VUR, moderate VUR associated with a complete duplication anomaly, severe renal scarring, or persistent VUR associated with an ectopic ureterocele, posterior urethral valves or a neuropathic bladder. The current perioperative management of children undergoing ureteroneocystostomy is detailed. In the future, the less invasive alternative of endoscopic therapy will need to be balanced against the changing understanding of the risk of VUR to the individual.

Ureteral stents are commonly used following urological procedures to maintain ureteral patency. However, alongside the benefits of the device, indwelling stents frequently cause significant patient discomfort (pain, urgency, frequency) and can become encrusted and infected. The importance of these sequelae is that they are not only bothersome to the patient but can lead to significant morbidity, urinary retention, ureteral damage, recurrent infections, pyelonephritis and sepsis. When these problems occur, stent removal or replacement alongside antibiotic, analgesic and/or other symptom-modifying therapies are essential to successfully treat the patient. In an attempt to prevent such morbidity, numerous approaches have been investigated over the past several decades to modify the stent itself, thereby affecting changes locally within the urinary tract without significant systemic therapy. These strategies include changes to device design, polymeric composition, drug-elution and surface coatings. Of these, drug-elution and surface coatings are the most studied and display the most promise for advancing ureteral stent use and efficacy. This article reviews these two strategies in detail to determine their clinical potential and guide future research in the area.

The most common cause of hydronephrosis in the pediatric age group is ureteropelvic junction-type hydronephrosis (UPJHN). Since the advent of widespread maternal ultrasound screening, clinical presentation of hydronephrosis associated with UPJ anomalies has changed dramatically. Today most cases are diagnosed in the prenatal period, and neonates present without signs or symptoms. For those who are not detected at birth, UPJHN eventually presents throughout childhood and even adulthood with various symptoms. Clinical picture of UPJHN highly depends on the presence and severity of obstruction, and whether it affects single or both kidneys. Abdominal or flank pain, abdominal mass, hematuria, kidney stones, urinary tract infections (UTI), and gastrointestinal discomfort are the main symptoms of UPJHN in childhood. Other less common findings in such patients are growth retardation, anemia, and hypertension. UTI is a relatively rare condition in UPJHN cases, but it may occur as pyelonephritis. Vesicoureteric reflux should be kept in mind as a concomitant pathology in pediatric UPJHN that develop febrile UTI. Although many UPJHN cases are known to improve over time, close clinical observation is critical in order to avoid irreversible kidney damage. The most appropriate approach is to follow-up the patients considering the presence of symptoms, the severity of hydronephrosis and the decrease in kidney function and, if necessary, to decide on early surgical intervention.
