Urinary diversion and reconstruction.
2000
Orthotopic bladder augmentation and substitution has been established as the standard procedure for urinary diversion in many institutions, with current studies reporting mainly on continence rates and procedure-associated complications, such as the risk of impairment of neobladder function by local tumor recurrences in the small pelvis. Similarly, in other types of continent diversion, such as continent cutaneous diversion and rectal reservoirs, current interest is primarily directed towards minimization of surgery-associated complications.
Appendiceal continence mechanisms in continent urinary diversion.
1996
The creation of a safe, reliable, and easy-to-perform continence mechanism remains one of the most important problems during continent urinary diversion. The advent of the use of the appendix as an efferent segment brought through the umbilicus has greatly facilitated surgical procedures with very favorable results. Our experience with the insitu appendix as an efferent segment during continent cutaneous urinary diversion using the Mainz-pouch I technique over the past 6 years revealed a markedly decreased complication rate of 3.2% as compared with 7.2% in patients who received an ileocecal intussusception nipple. The routine use of the appendix as a continence mechanism during continent ur…
Chronische thromboembolische pulmonale Hypertonie: Hämodynamische Auswirkungen der selektiven Pulmonalis-DSA mit nicht-ionischem Kontrastmittel
1998
PURPOSE This study evaluates the effects of pulmonary bolus injection of nonionic contrast medium on pulmonary artery pressure and resistance in patients with chronic thromboembolic pulmonary hypertension. METHODS In 39 patients (age 52 +/- 15) haemodynamic measurements were performed during bolus injection of nonionic contrast medium in a control group (I), in moderately severe (II) and severe pulmonary hypertension (III). RESULTS Initial inspiratory arrest caused significant pressure increase in all groups prior to bolus injection (delta PAsyst: 7.1 +/- 6.7 [I], 6.8 +/- 3.9 [II] und 7.2 +/- 7.9 mmHg p < 0.05). However, contrast bolus injection (25.1 +/- 2.3 ml iopamidol, 13.0 ml/s) caused…
Therapie thrombembolischer Verschlüsse der Unterschenkelarterien: Klinische Erfahrungen mit dem Angiojet®-Thrombektomiekatheter
1999
UNLABELLED To investigate the clinical impact of a new hydrodynamic thrombectomy catheter in thromboembolic occlusion of tibial arteries. METHOD 10 patients with thromboembolic occlusion of all tibial arteries were treated with the Angiojet thrombectomy device in order to reestablish blood flow. Depending on angiographic and clinical results of thrombectomy, additional thrombolysis, PTA, recanalization, or surgical bypass grafting was performed. RESULTS Antegrade blood flow in at least one tibial artery was reestablished in 6 cases with the thrombectomy device. However, additional treatment modalities were used in order to improve the outcome and to resolve adherent thrombi or to treat vess…
Hemodynamic Changes in Patients with Essential Hypertension after Therapy with Muzolimine
1987
Muzolimine is a new nonsulfonamide diuretic belonging to the pyrazolinone group (1).It is a potent high-ceiling diuretic agent like furosemide and bumetanide with long duration of action like thiazides (1, 2).
Einfluss von Typ-II-Endoleaks auf die Größenänderung und Hämodynamik experimenteller Aortenaneurysmen nach endovaskulärer Therapie
2003
PURPOSE To evaluate the aneurysm volume and the intra-aneurysmatic pressure and maximal pressure pulse (dp/dtmax) in completely excluded aneurysms and cases with endoleaks. MATERIALS AND METHODS In 36 mongrel dogs, experimental autologous aneurysms were treated with stent-grafts. All aortic side branches were ligated in 18 cases (group I) but were preserved in group II (n = 18). Aneurysm volumes were calculated from CT scans before and after intervention, and from follow-up CT scans at 1 week, 6 weeks and 6 months. Finally, for hemodynamic measurements, manometer-tipped catheters were introduced into the excluded aneurysm sac (group I and II), selectively in endoleaks (group II), and intral…
Clinical Syndromes, Pathogenesis, and Differential Diagnosis
1991
The temporal sequence of signs and symptoms in patients with cerebral ischemia provides important information for the analysis of underlying pathophysiologic mechanisms and in the search for a major hemodynamic or embolic cause. The signs reported and symptoms assessed are useful for localization of the ischemic region of the brain and identification of the affected vascular territories. Even in the case of a typical clinical picture the clinical findings alone are often insufficient for unequivocal anatomic and pathologic identification, however important they may be in the choice of diagnostic and therapeutic measures. In the first few hours after cerebral ischemia, determining the progno…
Photoaging evaluation by RGB images using a smartphone for photodynamic therapy assessment
2017
In this study was evaluated the photoaging of patients' skins by the processing of RGB images acquired with an optical system based on a smartphone. Two groups were approached: a younger and an older.
ESRA19-0275 The efficacy and safety of ultrasound-guided superficial cervical plexus block (SCPB) in patient undergoing thyroid surgery: a case report
2019
Background and aims The SCPB provides effective anesthesia and analgesia for the head and neck region. CPBs can be performed more safely and accurately under ultrasound guidance, which is used to easily identify various important landmarks. This case report was carried out to assess the efficacy of SCPB in reducing the intra and postoperative use of opioids/analgesics to control pain due to thyroidectomy. Methods Case report: 45-year-old woman, ASA II, underwent left hemithyroidectomy under general anesthesia (sevoflorane 2% and remifentanil TCI 0.7–1 ng/ml). Ultrasound-guided left superficial cervical plexus block (SCPB) was performed using levobupivacaine 10 ml 0.25%. Pain score was measu…
Focal Therapy for Prostate Cancer: Complications and Their Treatment
2021
Focal therapy is a modern alternative to selectively treat a specific part of the prostate harboring clinically significant disease while preserving the rest of the gland. The aim of this therapeutic approach is to retain the oncological benefit of active treatment and to minimize the side-effects of common radical treatments. The oncological effectiveness of focal therapy is yet to be proven in long-term robust trials. In contrast, the toxicity profile is well-established in randomized controlled trials and multiple robust prospective cohort studies. This narrative review summarizes the relevant evidence on complications and their management after focal therapy. When compared to whole glan…
