Differences in axial segment reorientation during standing turns predict multiple falls in older adults
2011
Author's version of an article in the journal: Gait and Posture. Also available from the publisher at: http://dx.doi.org/10.1016/j.gaitpost.2012.05.013 Background: The assessment of standing turning performance is proposed to predict fall risk in older adults. This study investigated differences in segmental coordination during a 360° standing turn task between older community-dwelling fallers and non-fallers. Methods: Thirty-five older adults age mean (SD) of 71 (5.4) years performed 360° standing turns. Head, trunk and pelvis position relative to the laboratory and each other were recorded using a Vicon motion analysis system. Fall incidence was monitored by monthly questionnaire over the…
Intraoperative identification and neurophysiologic parameters to verify pelvic autonomic nerve function during total mesorectal excision for rectal c…
2003
Abstract Background Preservation of parasympathetic and sympathetic nerves is required to avoid urogenital function disturbances after total mesorectal excision (TME) for rectal carcinoma. This study sought to determine whether intraoperative stimulation of parasympathetic nerves with monitoring of bladder contraction is useful in meeting this demand. Study design In a prospective pilot study, 17 patients, 11 men and 6 women, underwent TME with pelvic autonomic nerve preservation performed by an experienced surgeon. The parasympathetic nerves were stimulated by an electrostimulation device (Screener 3625, Medronic), and the resulting bladder contraction was measured manometrically in all pa…
Treatment of advanced prostatic cancer with parenteral cyproterone acetate: a phase III randomised trial.
1980
Summary— Forty-two patients with previously untreated T3/4 N1-4 MO/1 prostatic adenocarcinoma were treated with either cyproterone acetate (n=21; 300 mg intramuscularly per week) or oestradiol undecylate (n=21; 100 mg intramuscularly per month) after extensive staging which included open skeletal biopsy and pelvic lymphadenectomy in some cases. Subjective and objective parameters as well as signs of drug toxicity were recorded regularly. Evaluation after 6 months showed cyproterone acetate to be more effective in the following respects: (1) the significantly different castration effect as judged by plasma testosterone, (2) the objective voiding pattern and tumour response, with regression o…
Transrenal Ureteral Occlusion with a Detachable Balloon
1982
Transrenal ureteral occlusion using a detachable balloon was successfully employed to stop urinary flow in seven patients. The balloon was filled with low-viscosity silicone rubber and released in the distal ureter. Percutaneous nephrostomy provided external drainage. Indications were painful dysuria and large urinary fistulas in advanced pelvic malignancy. The method is preferable to ureteral embolization with tissue adhesive.
Pelvic floor stress response: reflex contraction with pressure transmission to the urethra.
1987
There is still controversy regarding the active role of striated intramural and periurethral muscles and their relative share of function for urinary continence under stress conditions. To evaluate the function of the periurethral muscles, we subjected a dog model to the physiologic stress condition created by sneezing. Simultaneous measurements of intravesical and three urethral pressures were obtained in the intact urinary tract and in a noncontractile substitute urethra, which was pulled through the pelvic floor and studied with and without additional pelvic floor suspension. The data clearly confirm the active role of striated sphincteric muscles for continence under stress conditions. …
Colon pouch (Mainz III) for continent urinary diversion
2007
OBJECTIVE To evaluate the use of a continent cutaneous pouch made exclusively of colon (Mainz pouch III), as excellent results with the Mainz pouch III in irradiated patients suggested that the indication for this type of urinary diversion could be extended. PATIENTS AND METHODS The outcome of 24 patients with continent cutaneous urinary diversions using colon segments (Mainz pouch III) was investigated retrospectively. Overall, 22 of the patients had a malignant disease and two a benign disease; 16 had a hysterectomy and pelvic exenteration for gynaecological tumours; two men with a rhabdomyosarcoma of the prostate had a radical cystoprostatectomy; one woman had pelvic exenteration for bla…
Fragility Fractures of the Pelvis.
2017
Fragility fractures of the pelvic ring (FFP) show an increasing frequency. Trauma mechanism, fracture morphology and degree of instability are different from those in high-energy pelvic ring lesions. Little is known about the optimal treatment strategy. A new comprehensive classification system with four categories of increasing instability is presented. It is connected with recommendations for type and invasiveness of treatment. FFP Type I are anterior instabilities only and can be treated conservatively. FFP Type II are non-displaced posterior lesions which can be treated conservatively or with percutaneous fixation. FFP Type III lesions are unilateral displaced posterior lesions which re…
Neuromodulation of the superior hypogastric plexus: a new option to treat bladder atonia secondary to radical pelvic surgery?
2009
Abstract Background The aim of this study is to report on the impact of neuromodulation to the superior hypogastric plexus in patients with bladder atonia secondary to pelvic surgery. Methods In 4 consecutive patients with bladder atonia secondary to pelvic surgery, we performed a laparoscopic implantation of a neurostimulator—LION procedure—to the entire superior hypogastric plexus. Results Of the 4 reported patients, 3 are able to partially void or empty their bladder. Conclusions If the presented results could be obtained in further patients and maintained in long-term follow-up, the LION procedure to the superior hypogastric plexus could change the management of bladder function in pati…
Review of the anatomic concepts in relation to the retrorectal space and endopelvic fascia: Waldeyer’s fascia and the rectosacral fascia
2008
Objective A precise anatomical study of the fascias within the retrorectal space is reported, analyzing and clarifying the anatomical concepts previously employed to describe Waldeyer’s and the rectosacral fascia. Method The pelvis was dissected in 15 cadavers (10 males and five females). All specimens were divided in the median sagittal plane including the middle axis of the anal canal, to allow a correct visualization of and access to the retrorectal space. Results The retrorectal space was limited anteriorly by the rectum and posterior mesorectum covered by a fine visceral fascia, and posteriorly by the sacrum covered by the parietal presacral fascia. The rectosacral fascia divided th…
Is there a role for percutaneous pelvic and acetabular reconstruction?
2007
The primary goal in the treatment of pelvic fractures is the restoration of haemodynamic stability. The secondary goal is the reconstruction of stability and symmetry of the pelvic ring. Percutaneous reconstruction can only be accepted if these goals are met. The type of definitive surgery is dependent of the degree of instability of the anterior and posterior pelvic ring. Retrograde transpubic screw fixation of pubic rami fractures is a good alternative to external fixation or plate and screw osteosynthesis. The technique of screw placement and image intensifier control is explained. Internal fixation of pure sacroiliac dislocations, fracture-dislocations of the sacroiliac joint and sacral…
