Mid-term results of autoinjection therapy for erectile dysfunction

Of over 300 patients with erectile dysfunction, 186 were selected for intracavernosal autoinjection therapy with a standardized papaverine-phentolamine mixture. A total of 156 patients performed 4,813 protocol autoinjections with a minimum of 10 and a maximum of 230 per patient. The dose that induced a full erection at the hospital could be reduced under home conditions by a mean of 35 per cent. Systemic side effects were not observed. The most inconvenient local side effects were prolonged erections in 24 patients in diagnostic use and in 3 patients in therapeutic use. These were treated easily without further consequences

Plasma N-Terminal Pro-Brain Natriuretic Peptide as Prognostic Marker in Fatal Cardial Decompensation with Sunitinib Malate Therapy

A 74-year-old man with metastatic renal cell carcinoma and a history of cardiac failure was treated with sunitinib malate. MUGA echocardiography could not detect a relevant change in the ejection fraction although the clinical situation of the patient worsened dramatically. The only parameter to hint at the deteriorated cardiac function was plasma N-terminal pro-brain natriuretic peptide (BNP). Finally, the patient died after only one cycle of sunitinib treatment. We propose to prospectively include BNP for the early detection of cardiovascular decompensation in high-risk patients. Future studies concerning the relevance of BNP in drug-related cardiotoxicity are urgently needed. Copyright (C) 2010 S. Karger AG, Base

Real-Time MRI of Continent and Stress Incontinent Male Patients after Orthotopic Ileal Neobladder

Introduction: The aim of this study was to correlate anatomic differences with continence status in male patients after cystoprostatectomy and ileal neobladder using real-time magnetic resonance imaging. Patients and Methods: Anatomic differences of 14 male patients (7 daytime continent and 7 stress incontinent) with ileal neobladder were determined by measuring the orthogonal distance of the bladder neck to the pubococcygeal line (PCL) to correlate anatomic differences with continence status. Results: The median distance of the bladder neck to PCL was +5.4 mm in continent patients before voiding whereas in incontinent patients it was +2 mm (p = 0.012). During the Valsalva maneuver, the median distance in continent patients was +4 and in incontinent patients -3 mm (p = 0.003). At the end of micturition, the median distance was +2.3 mm in continent patients and -12 mm in incontinent patients (p = 0.002). Conclusions: The bladder neck in incontinent patients showed more pronounced mobility in relation to the PCL during micturition and the Valsalva maneuver as compared to continent patients. In addition, the ileal neobladder was positioned significantly lower in the pelvis of incontinent patients. These preliminary results suggest that a stable bladder neck may be an important factor to reach full continence in patients with ileal neobladder. Copyright (C) 2011 S. Karger AG, Base

Erectile dysfunction due to ectopic penile vein

A total of 86/260 patients with erectile dysfunction had venous leakage as (joint) etiology. In 5 of 86 patients cavernosography showed pathologic cavernosal drainage only via an ectopic penile vein into the femoral vein. After ligation of this pathologic draining vessel, 4 of 5 patients regained spontaneous erectability. One patient with pathologic bulbocavernosus reflex latencies needed intracavernosal injection of vasoactive drugs for full rigidity

Diagnosis of venous incompetence inerectile dysfunction

In 26 of 214 patients with erectile dysfunction and proved venous incompetence by cavernosography, an additional bidirectional Doppler ultrasound was performed also to demonstrate venous outflow disturbances. All except one leakage in the superficial and deep dorsal veins could be demonstrated as well as 4 of 6 cavernosum-glandular shunts. Bidirectional Doppler ultrasound visualized a continuous retrograde blood flow from the sulcus coronarius to the root of the penis in superficial and deep dorsal penile veins as well as in ectopic penile veins, an orthograde blood flow in the sulcus coronarius in cavernosum-glandular shunt

Profile of temsirolimus in the treatment of advanced renal cell carcinoma

Temsirolimus is a potent inhibtor of the mammalian target of rapamycin (mTOR). In various clinical trials temsirolimus has shown an overall survival benefit for patients with metastatic renal cell carcinoma (mRCC). Thus it is approved for first-line therapy in high-risk mRCC patients. We discuss the indication, side effects and clinical implications of temsirolimus treatment
