Bladder function in the aged rat: a functional and morphological study.

This study was designed to characterize urinary bladder function in the aged rat (27 months of age). For comparative purposes, two different control groups were included into the experimental protocol: normal 6-month old and hyperdiuretic 6-month old rats. Increased threshold volume for micturition and increased bladder mass were found in both aged and hyperdiuretic rats. No difference in the amplitude of micturition contractions was detected between groups. In the aged rat, but not in the hyperdiuretic one, augmented threshold volume and bladder mass were associated with increased intravesical pressure at micturition and structural changes of intramural bladder innervation. When activated, the vesicovesical reflex did not show any change in terms of rate of isovolumetric contractions. In the aged rat, altered sensory information on the state of maximum fullness seems to play an important role in determining abnormal cystometric findings.

[Reconstructive surgery in complex hypospadias: therapeutic indications and technical considerations in 93 cases].

Perineo-scrotal hypospadias and the severe sequelae of a failed repair procedure are complicated cases. The present study describes our experience in the treatment of complex hypospadias, the new therapeutic possibilities, their indications and results. From 1981 to 1992, 93 children with complex hypospadias underwent surgery (53 underwent surgery for the first time and 40 for severe sequelae of a failed procedure). Excellent cosmetic results were achieved by surgery. For those undergoing hypospadias repair for the first time, we used a pedicled preputial flap following the Duckett (12 cases) or Standoli (41 cases) technique. For those with severe sequelae from a failed procedure, we utilized a pedicled skin flap (18 cases) or free flap of bladder mucosa or penile skin (22 cases). The overall complication rate was 50% (47 patients). Surgical repair of complex hypospadias is a relatively long and complicated procedure with a long learning curve and a high complication rate in the initial phase. Fistula is the most common complication, although closure is very simple due to the abundant, well vascularized, healthy tissue. Overall our results have been satisfactory, considering the severity of these cases.

Urological manifestations of acute appendicitis: report of two new cases.

Clinical manifestations of acute appendicitis are variegated and urologic symptoms may be the first manifestation of the disease. In 1985 we reported on 2 cases of acute appendicitis who presented with irritative bladder symptoms. Here we describe 2 new cases come to our observation because of hematuria and irritative bladder symptoms. A brief review of the literature is also carried out.

Video-urodynamic studies of minor voiding dysfunctions in children: an overview of 13 years' experience.

By the definition 'minor voiding dysfunctions' is understood children with a history of frequency, urgency, daytime wetting, squatting, and infrequent voiding, singly or in combination. Urinary tract infections (UTI) are often present but symptoms must also be present when the children are free of infection. The upper urinary tract is generally normal or has minor anomalies. Any evidence of infravesical obstruction, frank or occult neurogenic bladder, or emotional disturbances must be excluded. In this study we report 13 years' experience of video-urodynamic evaluation in children with minor voiding dysfunctions, with special reference to clinical information, morphofunctional correlations, relationship with recurrent UTI, vesico-ureteric reflux and dilatation of the upper urinary tract. According to our experience we estimate that about 60% of the patients evaluated in this study would not require a video-urodynamic evaluation today.

Ambulatory urodynamics: preliminary experience with vesico-urethral holter in children.

Detrusor function was evaluated by vesico-urethral holter (VUH), a computerized recording system (Urodec 500), in 17 children with lower urinary tract dysfunction. Eight had neurogenic bladders, eight had minor voiding dysfunction, and one was incontinent after posterior urethral valve ablation. VUH was technically satisfactory in, and acceptable to, all patients. It was more accurate in evaluating the type of urinary tract dysfunction than conventional urodynamics in 25% of the male patients and in 32.5% of the female patients.

Page kidney: a curable form of arterial hypertension. Case report and review of the literature.

A case report of arterial hypertension which occurred 5 years after a blunt renal trauma is presented. The physiopathology of this type of hypertension along with the diagnostic features and the therapeutic aspects are extensively discussed. The sudden appearance of hypertension in a young patient following trauma must suggest a Page kidney as one of the diagnostic possibilities.

[Neurogenic bladder caused by meningomyelocele in childhood: urodynamic pattern and treatment regimens].

The authors reviewed the records of 160 patients with neurogenic bladder secondary to myelomeningocele (MMC) treated at the Urology Department of the University of Padua during 1977-1988. All patients had been evaluated by excretory urography, urethrocystography and videocystomannometry (VCM). Urodynamic studies are fundamental in determining vesicosphincteric dysfunction and patients who are at high risk for early renal lesions. For this reason, the authors recommend urodynamic evaluation from the first year of the infant's life in order to institute treatment early. The therapeutic approach should aim at a) preserving renal function, b) achieving a socially acceptable degree of urinary continence, and c) protecting sexual function.

[Verrucous carcinoma of the penis. 2 cases and review of the literature].

The Authors report general experience with two cases of penis verrucous carcinoma. Such a neoplasia, slowly evolving and not infiltrating the surrounding tissues, needs deep biopsies for a correct diagnosis. Surgical excision of the tumor is the choice treatment at an early stage: at an advanced stage demolitive therapy consisting in a partial or total penectomy is necessary. Recent findings of frank malignant squamous cell carcinoma arising in verrucous carcinoma raise serious concerns on the use of conservative therapies.

[Occult urothelial neoplasia: diagnosis].

The authors report their experience in the diagnosis of the hidden neoplasia based on the follow-up of 27 patients with carcinoma in situ of the bladder. Urine cytology and mapping histology are the most effective examinations for the detection and follow up of an occult urothelial neoplasm.

[Treatment of bladder carcinoma in situ].

The authors report their experience in the treatment of 21 patients with carcinoma situ of the bladder. Although the safest therapy is radical cystectomy this operation nevertheless is extremely mutilating. For these reason initially we prefer local chemotherapy with ADM continued with careful follow-up of the patient.

[Uretero-nephroscopy. Personal experience].

The authors present the personal experience concerning with the use of the rigid ureteropyeloscopes. Two groups of patients have been studied. In the first one (14 subjects) the ureteropyeloscopy was performed either with diagnostic or therapeutic purposes, in the second one, just as upper urinary tract endoscopic control in patients previously submitted to distal ureteral resection and ureteroneocystostomy for urothelial neoplasia of the distal ureter. The authors presenting the personal results and complications, discuss the indications for the upper urinary tract endoscopy with rigid instruments.
