51/261. Systemic lupus erythematosus related transverse myelitis presenting longitudinal involvement of the spinal cord. Lupus-related transverse myelitis is a rare but serious complication. A 25-year-old Japanese woman with systemic lupus erythematosus (SLE) was admitted because of numbness of the face and left upper extremity, headache, and intermittent fever. Six days later, she developed tetraplegia. MRI of the spinal cord showed longitudinal high intensity signals from medulla oblongata to C5, and from Th12 to conus medullaris on T2-weighted image. These MRI findings were consistent with acute catastrophic neurological abnormalities. Despite administration of the combination of methylprednisolone and cyclophosphamide pulse therapies, as well as plasmapheresis, her condition did not improve. Any vasculopathy in addition to the autoimmune pathogenesis, and narrow therapeutic window may relate to the present refractory case. ( info) |
52/261. Urethral erosion of tension-free vaginal tape. Tension-free vaginal tape (TVT) is gaining popularity as a treatment of choice for women with stress urinary incontinence. It is a minimally invasive procedure with reported short operative and postoperative hospitalization times and low complication rates. We describe urethral erosion of a TVT sling material in a 55-year-old woman who presented with immediate postoperative urinary retention. The sling material was surgically removed and the urethral defect repaired, with the patient continent at the 3-month follow-up visit. A mid-urethral synthetic sling such as the TVT can erode into the urethra. ( info) |
53/261. Botulinum toxin urethral sphincter injection resolves urinary retention after pubovaginal sling operation. The management of prolonged urinary retention following pubovaginal sling surgery typically involves transvaginal urethrolysis for anatomical urethral obstruction. Brubaker recently reported on urethral sphincter abnormalities as a cause of postoperative urinary retention following either Burch suspension or a pubovaginal sling procedure. We report a case of functional urethral obstruction and detrusor acontractility following pubovaginal sling surgery that was successfully treated by botulinum A toxin urethral sphincter injection.

54/261. Lhermitte sign and urinary retention: atypical presentation of oxaliplatin neurotoxicity in four patients. BACKGROUND: Regimens combining oxaliplatin with fluorouracil and folinic acid are standard therapeutic options for patients with metastatic colorectal carcinoma. Oxaliplatin has a good safety profile, although it is responsible for dose-limiting neurotoxicity typically consisting of two distinct clusters of symptoms. Cold-induced distal paresthesiae occur during or shortly after infusion in most patients and are usually transient and mild. A persistent sensory peripheral neuropathy may develop with prolonged treatment, eventually causing superficial and deep sensory loss, sensory ataxia and functional impairment. methods: The authors report four cases of atypical neurotoxicity induced by oxaliplatin in patients treated for metastatic colorectal carcinoma. Two patients were male and two were female, with an age range of 52-59 years. RESULTS: Three patients experienced Lhermitte sign and two experienced urinary retention. In all cases, the cumulative dose of oxaliplatin was higher than 1000 mg (range, 1248-2040 mg). brain and spinal magnetic resonance imaging was performed in two patients and was normal. Somatosensory evoked potentials were recorded in two patients and suggested cervical dorsal column dysfunction. Symptoms resolved a few weeks after discontinuation of oxaliplatin. CONCLUSIONS: Lhermitte sign may be induced via a neurotoxic effect on the ascending axons of these T-shaped neurons. An atonic bladder may be the result of damage to the sensory portion of the sacral reflex arc, either in the dorsal roots, as for example in diabetic neuropathy, or in the posterior columns, as in tabes dorsalis. Alternatively, it may result from a paralysis of the parasympathetic fibers that control the bladder musculature. It is unclear at present whether the micturition difficulties observed in patients in the current series are due to sensory neuropathy or to autonomic neuropathy, event if the former hypothesis seems more likely, as autonomic neuropathy has not been previously observed with oxaliplatin, and its association with cisplatin is exceedingly rare and controversial.

55/261. urinary retention during the second trimester of pregnancy: a rare cause. Acute urinary retention during pregnancy is rare. Retention secondary to an impacted, gravid uterus is an emergency. Retroversion of the uterus, a history of pelvic inflammatory disease, and large fibroids are predisposing factors. The enlarging gravid uterus and uterine fibroids may trap the uterus inside the pelvic ring, preventing it from ascending into the abdominal cavity; furthermore, a history of inflammatory disease may trap the fundus of the uterus within scar tissue that also may prevent the enlarging, gravid uterus from ascending into the abdominal cavity. The impacted uterus should be manually replaced in the anterior position. Clean intermittent catheterization and placement of a vaginal pessary are temporizing measures. A knowledge of the causes of urinary retention during pregnancy can help prevent spontaneous abortion and other devastating consequences that can arise as a result of a delay in the diagnosis.

| Acute urinary retention is an uncommon diagnosis in childhood, and is associated with a variety of causes. Congenital bladder diverticula, occurring almost exclusively in boys, is not a rare entity. However, acute urinary retention is an extremely rare complication of congenital bladder diverticulum. A boy with acute urinary retention caused by obstructing bladder diverticula is presented, and the surgical approach is discussed. ( info) |
57/261. Laparoscopic ileovesicostomy. PURPOSE: We present our initial experience with laparoscopic ileovesicostomy for managing neurogenic bladder. MATERIALS AND methods: A 5 port transperitoneal approach was used for laparoscopic ileovesicostomy. After bladder preparation a 17 cm. ileal segment was harvested and used as the urinary conduit. Ileovesical anastomosis was formed using intracorporeal suturing and knot tying techniques. RESULTS: operative time was 4 hours. blood loss was less than 100 ml. Physical activity and oral intake resumed on postoperative day 1 and the patient was discharged home on postoperative day 3. The postoperative narcotic requirement was 4 mg. morphine sulfate equivalent. There were no intraoperative or postoperative complications. CONCLUSIONS: Laparoscopic ileovesicostomy in this initial experience was associated with acceptable operative time and minimal postoperative morbidity. It may serve as an excellent minimally invasive alternative to conventional open ileovesicostomy. ( info) |
58/261. Acute urinary retention as an unusual manifestation of aseptic meningitis. A formerly healthy 32-year-old woman was hospitalized for a closer examination of undiagnosed fever with mild headache. Despite lack of distinct findings on physical and laboratory examinations at admission, she suddenly developed anuresis due to acontractile neurogenic bladder. On the basis of her symptoms and the faint nuchal rigidity revealed later, as well as the results of cerebrospinal fluid analyses, a diagnosis of aseptic meningitis was eventually reached. While aseptic meningitis subsided within 3 weeks, about 10 weeks, including a 26-day period of anuria, was necessary for complete restoration of normal voiding function, necessitating intermittent self-catheterization. Acute urinary retention should be considered an uncommon but critical manifestation of aseptic meningitis. ( info) |
59/261. Treatment of a complete lower urinary tract obstruction secondary to an expandable foam sealant. We present a unique case of an iatrogenic complete lower urinary tract obstruction with an expandable foam sealant. A 41-year-old man presented in urinary retention 36 hours after self-injecting his urethra with the foam sealant, which could be palpated throughout his entire urethra. The sealant was removed from the distal urethra in numerous fragments with a hemostat and cystoscopically. A perfect mold of the bladder and prostatic urethra were removed by suprapubic cystotomy. cystoscopy 2 months later demonstrated a mild bulbar urethral stricture, but normal bladder mucosa. The cystoscopy at 6 months was normal. ( info) |
