An unusual case of ureteral ectopia in the seminal vesicle: diagnosis and surgical management.

1999

We report the case of a young man who presented with numerous episodes of ipsilateral epididymitis. Selected imaging studies with consideration of urogenital embryology lead to the rare diagnosis of a dysplastic kidney with ureteral ectopia in the seminal vesicle. After nephroureterectomy and vesiculectomy, convalescence was uneventful. No specific symptoms, equivocal diagnostic findings and the small number of patients limit the surgical experience in diseases of the seminal vesicle. Suprainguinal extravesical extirpation, however, appears to be an excellent operative approach in cases of unilateral seminal vesicle cysts.

Sacral neurostimulation and neuromodulation in urological practice

2000

The problems associated with treating various forms of lower tract dysfunction by electrical stimulation are reflected in the many years of basic and clinical research in this area. However, better understanding of both neuroanatomy and neurophysiology, and development of new technologies have led to further application of electrical current to restore impaired bladder function. Contemporary knowledge of the potential for both sacral neurostimulation and neuromodulation as a therapeutic option for lower urinary tract dysfunction is reviewed.

RETROVESICAL MASS IN MEN

1999

We review the differential diagnosis and treatment of retrovesical masses in men.During the last 8 years 21 male patients 3 to 79 years old (mean age 47.1) presented with symptoms or signs of a retrovesical mass. Clinical features and diagnostic findings were reviewed, and related to surgical and histopathological findings.The retrovesical masses included prostatic utricle cyst in 3 cases, prostatic abscess in 1, seminal vesicle hydrops in 6, seminal vesicle cyst in 2, seminal vesicle empyema in 3, large ectopic ureterocele in 1, myxoid liposarcoma in 1, malignant fibrous histiocytoma in 1, fibrous fossa obturatoria cyst in 1, hemangiopericytoma in 1 and leiomyosarcoma in 1. In 17 patients …

Orthotopic bladder augmentation and substitution.

1999

Orthotopic bladder augmentation or substitution using intestinal segments has become a standard procedure for many disorders that cause a loss of functional or anatomical bladder capacity. From the technical point of view, reservoir configuration by detubularizing the intestinal segments is the general practice. Various techniques exist, depending which types of segments and which techniques of ureteral implantation are used. Common problems include urinary incontinence, retention, metabolic disorders, and the possibility of secondary malignancies. As a result, research has been conducted into utilizing tissues other than intestine for bladder augmentation or substitution.

Sacral neuromodulation for treatment of lower urinary tract dysfunction

2000

Despite initial reservations, sacral neuromodulation has begun to develop as a new therapeutic tool for the treatment of lower urinary tract dysfunction. It bridges the gap between conservative treatment options and highly invasive procedures, such as urinary diversion. At present, there are no clinical variables that can reliably predict the efficacy of neuromodulation in an individual patient. All patients, regardless of indication, must therefore undergo a test stimulation before they can be offered chronic sacral neuromodulation with an implanted system. Evaluations in various clinical trials have confirmed that sacral neuromodulation, based on unilateral sacral foramen electrode implan…

Chronic sacral neuromodulation for treatment of neurogenic bladder dysfunction: long-term results with unilateral implants

2001

Abstract Objectives. To investigate the therapeutic value of sacral neuromodulation in patients with neurogenic disorders in whom conservative treatment options were unsuccessful. Neurogenic disorders may result in various forms of lower urinary tract dysfunction. Methods. Twenty-seven patients (19 women, 8 men) aged 18 to 63 years (mean 44.9 years) were subjected to percutaneous test stimulation of the sacral spinal nerves. Their urologic symptoms consisted of bladder storage failure (n = 15) due to detrusor hyperreflexia and/or bladder hypersensitivity, failure to empty due to detrusor areflexia (n = 11), and combined bladder hypersensitivity and detrusor areflexia (n = 1). Twelve patient…

The impact of sacral root anatomy on selective electrical stimulation for bladder evacuation.

1998

Although different structures have been studied with electrostimulation to elicit bladder evacuation, only the sacral root remains feasible for clinical application at present. However, the resultant concomitant contractions of the bladder and sphincteric muscles have been the principal problem over the last few decades. Attempts to identify fibers within the sacral ventral root that innervate the detrusor predominantly have been made by microsurgery alone or in combination with advanced electrical blocking techniques. This article evaluates our past and present efforts to achieve voiding in light of the mixed nature of sacral root anatomy.

Sacral bladder denervation for treatment of detrusor hyperreflexia and autonomic dysreflexia

2001

Objectives. Detrusor hyperreflexia after spinal cord injury may cause urinary incontinence and chronic renal failure. In patients refractory to conservative treatment and not eligible for ventral sacral root stimulation for electrically induced micturition, we investigated the therapeutic value of sacral bladder denervation as a stand-alone procedure. Methods. Nine patients (8 men and 1 woman) between 21 and 58 years old (mean 30.2) with traumatic suprasacral spinal cord lesions underwent sacral bladder denervation for treatment of detrusor hyperreflexia and/or autonomic dysreflexia. Results. Detrusor hyperreflexia and autonomic dysreflexia were eliminated in all cases. Bladder capacity inc…

Transposition of the left renal vein for treatment of the nutcracker phenomenon: long-term follow-up

2002

Abstract Objectives To assess the therapeutic value of left renal vein transposition for treatment of the nutcracker phenomenon in long-term follow-up. Methods Eight patients (4 women and 4 men) between 23 and 58 years old (mean 39.1) underwent transposition of the left renal vein for treatment of the nutcracker phenomenon associated with recurrent gross hematuria and flank pain. The postoperative follow-up was 41 to 136 months (mean 66.4). Results No perioperative complications were encountered. The postoperative complications comprised deep vein thrombosis (n = 1), retroperitoneal hematoma necessitating surgical revision (n = 1), and paralytic ileus that resolved with conservative managem…

Low Urethral Pressure Profile - Clinical Implications

2001

The clinical impact of urethral pressure profilometry (UPP) has been a main urological topic over the past three decades. Exaggareted expectations and differing techniques with incongruent results caused a controversial appearance. However, since the UPP is the only method to measure directly aspects of the urethral closure function, all types of sphincteric urinary incontinence represent indications for this measurement. Based on long-term experience this paper aims to discuss the various complexes regarding the urethral pressure profilometry. The significance of the urethral closure function for urinary continence and the urodynamic relevance of active and passive pressure transmission ar…
