RESUMO
STUDY DESIGN: Retrospective and prospective observational. OBJECTIVE: The main objective of this study was to analyse suicide attempt as a cause of traumatic spinal cord injury (tSCI) and suicide as a cause of death after tSCI. SETTING: This study was conducted at two British spinal centres, Stoke Mandeville and Southport. METHODS: Long-term survival of patients who were newly admitted between 1991 and 2010, had survived the first post-injury year and had neurological deficit on discharge. Follow-up was discontinued on 31 December 2014. RESULTS: Among the 2304 newly admitted cases of tSCI, suicide attempt was the cause of injury in 63 cases (2.7%). By the end of 2014 there were 533 deaths of which 4.2% deaths were by suicide, with 91% of suicides happening in the first 10 years post injury. Multiple logistic regression analyses showed a higher mortality odds ratio (OR=4.32, P<0.001) and a much higher suicide OR (9.46, P<0.001) for persons injured in suicide attempts when compared with all other SCI aetiologies. The overall age-standardised suicide mortality rate was 62.5 per 100 000 persons per year (95% confidence interval=36.4-88.6), five times higher than the general population suicide rate for England and Wales in 2014 (12.2 per 100 000). CONCLUSIONS: Suicide attempt was the cause of tSCI in 2.7% of the sample and suicide was the cause of death in 4.2% of all deaths. The overall mortality and death by suicide were significantly higher in persons whose tSCI was caused by an attempted suicide when compared with the rest of the sample. Continued psychological attention following SCI, especially to those who were injured by suicide attempt, is warranted.

DESIGN: Retrospective and prospective observational. OBJECTIVE: Analyse causes of death after traumatic spinal cord injury (tSCI) in persons surviving the first year post injury, and establish any trend over time. SETTING: Two spinal centres in Great Britain. METHODS: The sample consisted of 5483 patients with tSCI admitted to Stoke Mandeville and Southport spinal centres who were injured between 1943 and 2010, survived first year post injury, had residual neurological deficit on discharge and were British residents. Mortality information, including causes of death, was collected up to 31 December 2014. Age-standardised cause-specific mortality rates were calculated for selected causes of death, and included trends over time and comparison with the general population. RESULTS: In total, 2322 persons (42.3% of the sample) died, with 2170 (93.5%) having a reliable cause of death established. The most frequent causes of death were respiratory (29.3% of all certified causes), circulatory, including cardiovascular and cerebrovascular diseases (26.7%), neoplasms (13.9%), urogenital (11.5%), digestive (5.3%) and external causes, including suicides (4.5%). Compared to the general population, age-standardised cause-specific mortality rates were higher for all causes, especially skin, urogenital and respiratory; rates showed improvement over time for suicides, circulatory and urogenital causes, no significant change for neoplasms, and increase for skin and respiratory causes. CONCLUSIONS: Leading causes of death after tSCI in persons surviving the first year post injury were respiratory, circulatory, neoplasms and urogenital. Cause-specific mortality rates showed improvement over time for most causes, but were still higher than the general population rates, especially for skin, urinary and respiratory causes.

STUDY DESIGN: Retrospective and prospective observational. OBJECTIVES: Analyse long-term survival after traumatic spinal cord injury (SCI) in Great Britain over the 70-year study period, identify mortality risk factors and estimate current life expectancy. SETTING: Two spinal centres in Great Britain. METHODS: The sample consisted of patients with traumatic SCI injured 1943-2010 who survived the first year post-injury, had residual neurological deficit on discharge and were British residents. Life expectancy and trends over time were estimated by neurological grouping, age and gender, using logistic regression of person-years of follow-up combined with standard life table calculations. RESULTS: For the 5483 cases of traumatic SCI the mean age at injury was 35.1 years, 79.7% were male, 31.1% had tetraplegia AIS/Frankel ABC, 41.2% paraplegia ABC,and 27.7% functionally incomplete lesion (all Ds). On 31 December 2014, 54% were still alive, 42.3% had died and 3.7% were lost to follow-up. Estimated life expectancies improved significantly between the 1950s and 1980s, plateaued during the next two decades, before slightly improving again since 2010. The estimated current life expectancy, compared with the general British population, ranged from 18.1 to 88.4% depending on the ventilator dependency, level and completeness of injury, age and gender. CONCLUSIONS: Life expectancy after SCI improved significantly between the 1950s and 1980s, plateaued during the 1990s and 2000s, before slightly improving again since 2010, but still remains well below that of the general British population.

BACKGROUND: Disability scales do not enable the transmission of concise, meaningful and daily function description for clinical purposes. STUDY DESIGN: Cross-sectional statistical analysis of 328 patients' Spinal Cord Independence Measure (SCIM) III item scores (SIS). OBJECTIVE: To develop a concise and clinically interpretable data-based characterization of daily task accomplishment for patients with spinal cord lesions (SCLs). SETTING: Multi-center study at 13 spinal units in 6 countries. METHODS: Patients were grouped into clusters characterized by smaller differences between the patients' SIS within the clusters than between their centers, using the k-medoides algorithm. The number of clusters (k) was chosen according to the percent of SIS variation they explained and the clinical distinction between them. RESULTS: Analysis showed that k=8 SIS clusters offer a good description of the patient population. The eight functional clusters were designated as A-H, each cluster (grade) representing a combination of task accomplishments. Higher grades were usually (but not always) associated with patients implementing more difficult tasks. Throughout rehabilitation, the patients' functional grade improved and the distribution of patients with similar functional grades within the total SCIM III score deciles remained stable. CONCLUSIONS: A new classification based on SIS clusters enables a concise description of overall functioning and task accomplishment distribution in patients with SCL. A software tool is used to identify the patients' functional grade. Findings support the stability and utility of the grades for characterizing the patients' functional status.

STUDY DESIGN: Multicenter international cohort study. OBJECTIVE: The objective of this study was to establish target values for Spinal Cord Independence Measure (SCIM) III scoring in rehabilitation for clinically complete spinal cord lesion (SCL) neurological levels. SETTING: In total, 13 spinal cord units in six countries from North America, Europe and the Middle East were taken. METHODS: Total SCIM III scores and gain at discharge from rehabilitation were calculated for SCL levels in 128 patients with American Spinal Injury Association Impairment Scale (AIS) grade A on admission to rehabilitation. RESULTS: Median, quartiles, mean and s.d., values of discharge SCIM III scores and SCIM III gain for the various SCL levels are presented. Total SCIM III scores and gain were significantly correlated with the SCL level (r=0.730, r=0.579, P<0.001). CONCLUSIONS: Calculated discharge SCIM III scores can be used as target values for functional achievements at various neurological levels in patients after AIS A SCL. They are generally, but not always, inversely correlated with SCL level.

STUDY DESIGN: A multi-center international cohort study. OBJECTIVE: To evaluate the reliability and validity of the third version of the Spinal Cord Independence Measure (SCIM III), separately for patients with traumatic spinal cord lesions (SCLs). SETTING: A total of 13 spinal cord units in six countries from North America, Europe and the Middle-East. METHODS: SCIM III and Functional Independence Measure (FIM) were assessed for 261 patients with traumatic SCLs, on admission to rehabilitation and before discharge, by two raters. Conventional statistical measures were used to evaluate the SCIM III reliability and validity. RESULTS: In almost all SCIM III tasks, the total agreement between the paired raters was >80%. The κ coefficients were all >0.6 and statistically significant. Pearson's coefficients of the correlations between the paired raters were >0.9, the mean differences between raters were nonsignificant and the intraclass correlation coefficients (ICCs) were ≥ 0.95. Cronbach's α values for the entire SCIM III scale were 0.833-0.835. FIM and SCIM III total scores were correlated (r=0.84, P<0.001). SCIM III was more responsive to changes than FIM. In all subscales, SCIM III identified more changes in function than FIM, and in 3 of the 4 subscales, differences in responsiveness were statistically significant (P<0.02). CONCLUSION: The results confirm the reliability and validity of SCIM III for patients with traumatic SCLs in a number of countries.

PURPOSE: To examine the third version of the Spinal Cord Independence Measure (SCIM III) for reliability and validity in a multi-center cohort study. METHOD: Four hundred and twenty-five patients with spinal cord lesions from 13 spinal cord units in six countries from three continents were assessed with SCIM III and the Functional Independence measure (FIM) on admission to rehabilitation and before discharge. RESULTS: Total agreement between raters was above 80% in most SCIM III tasks, and all kappa coefficients were statistically significant (P<0.001). The coefficients of Pearson correlation between the paired raters were above 0.9, and intraclass correlation coefficients were above 0.94. Cronbach's alpha was above 0.7. The coefficient of Pearson correlation between FIM and SCIM III was 0.790 (P<0.01). SCIM III was more responsive to changes than FIM in the subscales of Respiration and sphincter management and Mobility indoors and outdoors. CONCLUSIONS: The results support the reliability and validity of SCIM III in a multi-cultural setup. Despite several limitations of the study, the results indicate that SCIM III is an efficient measure for functional assessment of SCL patients and can be safely used for clinical and research trials, including international multi-center studies.

BACKGROUND: A delay in diagnosis or a misdiagnosis may occur in patients with spinal cord injury (SCI) or spinal bifida as typical symptoms of a clinical condition may be absent because of their neurological impairment. CASE PRESENTATION: A 29-year old male, who was born with spina bifida and hydrocephalus, became unwell and developed a swelling and large red mark in his left loin eighteen months ago. Pyonephrosis or perinephric abscess was suspected. X-ray of the abdomen showed left-sided staghorn calculus. Since ultrasound scan showed no features of pyonephrosis or perinephric abscess, he was prescribed a prolonged course of antibiotics for infection presumed to arise from the site of metal implant in spine. He developed a discharging sinus, following which the loin swelling and red mark subsided. About three months ago, he again developed a red mark and minimal swelling in the left loin. Ultrasound scan detected no abnormality in the renal or perinephric region. Therefore, the red mark and swelling were attributed to pressure from the backrest of his chair. Five weeks later, the swelling in the left loin burst open and a large stone was extruded spontaneously. An X-ray of the abdomen showed that he had extruded the central portion of the staghorn calculus from left kidney. With hindsight, the extruded renal calculus could be seen lying in the subcutaneous tissue of left loin lateral to the 10th rib in the X-ray of abdomen, which was taken when he presented with red mark and minimal swelling. CONCLUSION: This case illustrates how mistakes in diagnosis could occur in spinal cord injury patients, and highlights the need for corrective measures to reduce urological errors in these patients. Voluntary reporting of urological errors is recommended to facilitate learning from our mistakes. In the patients who have marked spinal curvature, ultrasonography of kidneys and perinephric region may not be entirely reliable. As clinical symptoms and signs may be non-specific in SCI patients, they require prompt, detailed and occasionally, repeated investigations. A joint team approach by health professionals belonging to various medical disciplines, which is strengthened by frequent, informal and honest discussions of a patient's clinical condition, is likely to reduce urological errors in SCI patients.

BACKGROUND: To present a protocol of a prospective, cohort study in which four groups of spinal cord injury (SCI) patients will participate. (Patients with indwelling urethral catheter; patients who perform intermittent catheterisation without wearing a penile sheath; patients who perform intermittent catheterisation and wear penile sheath as well; and patients with penile sheath drainage). OBJECTIVES: (1) What is the incidence of symptomatic urinary infection in men with spinal cord injury who use different types of bladder drainage? (2) Which are predisposing factors for the occurrence of symptomatic urinary infection in men with spinal cord injury who practise different methods of bladder drainage? (3) What is the incidence of catheter and urinary drainage system-related adverse events in the four groups of SCI patients? PATIENTS: The criteria for inclusion are as follow: (1) Male patients with neuropathic bladder due to spinal cord injury, who are registered with the Regional Spinal Injuries Centre, Southport, England. (2) Age: 18 years or above. (3) Patients who are willing to give informed consent for participation in the study. (4) Patients willing to be contacted every two weeks by a staff of the spinal unit for 36 months. (5) Patients who are willing to maintain an accurate record of adverse events related to urinary catheter and urinary drainage system and predisposing factors for the occurrence of symptomatic urinary infection. (6) Patients, who are stabilised in a particular method of bladder drainage, and therefore, unlikely to make a permanent change in the method of bladder drainage (e.g. from penile sheath drainage to the use of long-term indwelling catheter) during a foreseeable future. METHODS: The participants will be observed for a period of 36 months. A staff of the spinal injuries unit will contact the participants by telephone every two weeks on a mutually agreed day and time. The information obtained during this standardised telephonic interview conducted once in two weeks will be entered in a database. When a participant develops symptom(s) suggestive of urinary infection, he will undergo urine and blood tests, and imaging studies of the urinary tract. CONCLUSION: This study will provide information regarding the occurrence of symptomatic urinary infection, predisposing factors for development of urinary infection, and adverse events related to urinary catheter and urinary drainage system in SCI patients using different methods of bladder drainage.

Urine leakage from the umbilicus was observed while expressing urine by the Crede manoeuvre in a three-year-old tetraplegic girl with a chronically distended urinary bladder. Intravenous urography (IVU) revealed bilateral hydroureteronephrosis with markedly distended urinary bladder. Regular three hourly intermittent catheterization was advised, and the parents and carers of this child agreed to perform catheterization. There was cessation of urine leak within 48 hours of urethral drainage. Cystography performed two weeks later showed no vesicoureteric reflux; vesicoumbilical fistula was no longer demonstrable. Follow-up IVU, performed after eight and half months of regular intermittent catheterization, showed regression of hydroureteronephrosis. We believe that urine leakage from the umbilicus served two important protective functions in this child, viz. (1) it prevented possible vesical or renal rupture; (2) the striking clinical symptom of urine leak from the umbilicus focussed the attention of the carers to the underlying serious condition of the urinary tract. Further, this case demonstrates that regression of marked hydroureteronephrosis can be achieved by intermittent catheterization performed at regular intervals by devoted parents/carers, in selected cases of spinal cord injury with neuropathic bladder, and vesical outlet obstruction, thus obviating the need for any form of temporary or permanent urinary diversion.

STUDY DESIGN: A retrospective study with review of literature. OBJECTIVES: (1) To report the management and outcome of a series of six cases of transverse sacral fractures. (2) To review the literature and see the influence of the type of treatment on the neurological outcome, in particular, of the bladder and bowel and to identify the possible factors determining this outcome. SETTING: Regional spinal injury Unit, Southport, UK. METHODS: Six patients with transverse sacral fractures were identified and their case notes were reviewed. The follow-up period was 4 to 17 years. A review of literature was carried out and publications that reported the outcome of function of bowel and urinary bladder were considered for the study. RESULTS: Five of our six patients had cauda equina syndrome. Five cases were managed conservatively and one case surgically. Bladder and bowel function did not improve in three out of five cases. A review of English literature identified 18 (60 cases) of the 25 publications mentioning the outcome of bladder and bowel function. Of these, 47 cases were managed surgically, with the improvement of bladder and bowel function in 34 cases. Rest of the 13 cases were treated conservatively, with the improvement of bladder and bowel function in 10 cases. CONCLUSION: There is no statistical evidence of benefit of either surgical or conservative management on the outcome of bladder and bowel function. Presence of a severe angulation, displacement of fracture and neurotomesis dictate poor prognosis.

BACKGROUND: A third version of the Spinal Cord Independence Measure (SCIM III), made up of three subscales, was formulated following comments by experts from several countries and Rasch analysis performed on the previous version. OBJECTIVE: To examine the validity, reliability, and usefulness of SCIM III using Rasch analysis. DESIGN: Multicenter cohort study. SETTING: Thirteen spinal cord units in six countries from North America, Europe, and the Middle-East. SUBJECTS: 425 patients with spinal cord lesions (SCL). INTERVENTIONS: SCIM III assessments by professional staff members. Rasch analysis of admission scores. MAIN OUTCOME MEASURES: SCIM III subscale match between the distribution of item difficulty grades and the patient ability measurements; reliability of patient ability measures; fit of data to Rasch model requirements; unidimensionality of each subscale; hierarchical ordering of categories within items; differential item functioning across classes of patients and across countries. RESULTS: Results supported the compatibility of the SCIM subscales with the stringent Rasch requirements. Average infit mean-square indices were 0.79-1.06; statistically distinct strata of abilities were 3 to 4; most thresholds between adjacent categories were properly ordered; item hierarchy was stable across most of the clinical subgroups and across countries. In a few items, however, misfit or category threshold disordering were found. CONCLUSIONS: The scores of each SCIM III subscale appear as a reliable and useful quantitative representation of a specific construct of independence after SCL. This justifies the use of SCIM in clinical research, including cross-cultural trials. The results also suggest that there is merit in further refining the scale.

STUDY DESIGN: Retrospective analysis. OBJECTIVES: To assess the effect of repeated electro-ejaculation on the sperm quality in spinal cord injured men. SETTING: Regional Spinal Injuries Unit, Southport, UK and Hewitt Center for Reproductive Medicine, Liverpool, UK. METHOD: Retrospective, observational study of men with spinal cord injuries undergoing repeated electro-ejaculation as a part of fertility treatment. RESULT: There was no improvement in the volume, sperm concentration, motility or the total motile count in the successive antegrade and retrograde samples following repeated electro-ejaculations. CONCLUSION: Electro-ejaculation is an invasive procedure and its use should be restricted to obtaining semen sample for carrying out assisted conception procedures only.

STUDY DESIGN: A case report. OBJECTIVE: To raise awareness among spinal cord clinicians of the possible carcinogenic effect of phenoxybenzamine and of the rare occurrence of small cell carcinoma in the neuropathic bladder. SETTING: Regional Spinal Injuries Centre and District General Hospital, Southport, Merseyside, United Kingdom. CASE REPORT: A 28-year-old man sustained a fracture dislocation of L-1 with consequent paraplegia (ASIA impairment scale A). Phenoxybenzamine treatment enabled his indwelling catheter to be discarded in favour of a penile sheath, but it caused unacceptable dizziness and was stopped after 7 years. After 20 years, he developed chronic lymphocytic leukaemia, which was treated with chlorambucil and fludarabine. After 2 years, investigation of bilateral hydronephrosis revealed a primary small cell carcinoma of the bladder with coexistent squamous dysplasia. Uraemia supervened and, declining active treatment, the patient died 3 weeks after diagnosis. CONCLUSION: Phenoxybenzamine, a known carcinogen in rodents, is likely also to be carcinogenic in humans, and patients with spinal cord injury who have received the drug for any significant period of time, need close follow-up to allow early detection of cancer. Phenoxybenzamine should not be prescribed on a long-term basis, and should instead be replaced with a selective alpha-blocker.

STUDY DESIGN: Case report. SETTING: Northwest Regional Spinal Injuries Unit, Southport, UK and Reproductive Medicine Unit, Liverpool Women's Hospital, Liverpool, UK. CASE REPORT: A 28-year-old man suffered from paraplegia on sustaining a fall. Fertility preservation was an important aspect of his treatment and electro-ejaculation and cryopreservation of sperm was possible within days of sustaining the fall. The sperm samples obtained subsequently showed a rapid decline in quality. Frozen sperm from the first normal ejaculate obtained soon after the injury was used for assisted reproduction and has resulted in an ongoing pregnancy. CONCLUSION: This case highlights the importance of collection and freezing of seminal fluid within 2 weeks of spinal cord injury (SCI), or earlier to improve fertility outcomes in spinal cord-injured men, as the clinical stability of the patient may allow.

STUDY DESIGN: Two case reports of male football players who sustained injury to cervical spinal cord as a direct result of the sport. OBJECTIVE: To raise the awareness that playing football (soccer), a very popular sport, may cause injury to the cervical spinal cord with dire consequences, albeit rarely. SETTING: North West Regional Spinal Injuries Centre, Southport, UK. CASE REPORT: We report two male football players, who sustained injury to the cervical spine and developed tetraplegia as a direct result of the sport. Case 1: A 21-year-old football player was tackled from behind while running with the football, he lost his balance and landed on his head resulting in burst fracture dislocation of C5/C6 associated with immediate onset of complete tetraplegia (ASIA-A). Case 2: A 24-year-old football player collided, head first, with his own team goalkeeper, causing a hyperextension of neck. He developed motor complete tetraplegia at C5 level, with some sensation sparing below the level of injury (ASIA-B). CONCLUSION: Injury to the cervical spinal cord is known to occur in some team contact sports such as rugby and American football. Over time the laws and the preparation of the athletes for these games have been changed in order to minimize the neck injuries. What might not be appreciated is that playing football (soccer), a very popular sport worldwide, may cause injury to cervical spinal cord with dire consequences.

STUDY DESIGN: A case report. SETTING: Regional Spinal Injuries Centre, Southport, UK. CASE REPORT: A 56-year-old male with complete paraplegia at T-4 underwent visual internal urethrotomy of bulbous urethral stricture with a cold knife at 12 o'clock position. There was brisk arterial bleeding. Despite receiving antibiotics, this patient developed hypotension, tachycardia and tachypnoea. He was resuscitated and mechanical ventilation was instituted. After he recovered from this life-threatening episode of urinary tract-related sepsis, colour Doppler ultrasound imaging of bulbous urethra was performed to locate urethral arteries. In the bulbous urethra, single urethral artery was seen at 12 o'clock position. CONCLUSION: Since the sites of urethral arteries vary among patients, it is advisable to assess individually the location of urethral arteries preoperatively and plan the site of incision accordingly. Persons with injury to cervical or upper dorsal spinal cord have decreased cardiac and respiratory reserve as well as alteration in immune function. Therefore, all possible measures should be taken to prevent acute blood loss and bacteraemia in this group of patients.

STUDY DESIGN: Clinical case report with comments by colleagues from Sweden, Poland, Spain, Brazil, Japan, Belgium and Switzerland. OBJECTIVES: To discuss the role of disodium etidronate therapy for prevention of calcium phosphate vesical calculi in persons with spinal cord injury, who have hypercalciuria and biochemical evidence of increased bone resorption. SETTING: Regional Spinal Injuries Centre, Southport, UK. METHODS: A 21-year-old male sustained paraplegia (T-10; ASIA scale: A) in a road traffic accident in June 2001. He had an indwelling urethral catheter until the end of August 2001, when he started self-catheterisation. He developed bladder stones and electrohydraulic lithotripsy (EHL) was performed in May 2002. All stone fragments were removed. Recurrence of vesical calculi was noted in October 2002. These stones were fragmented by lithoclast lithotripsy in two sessions, in December 2002 and February 2003; all stone fragments were removed at the end of the second session. This patient reverted to indwelling catheter drainage when vesical calculi recurred. In September 2003, X-ray of the abdomen showed recurrence of vesical calculi. By February 2004, the stones had increased in size and number. EHL of vesical calculi was again performed in April 2004. Complete clearance was achieved. RESULTS: A 24-h urinalysis detected hypercalciuria--18.7 mmol/day (reference range: 2.5-7.5). Biochemical analysis of vesical calculus revealed calcium phosphate (85%) and magnesium ammonium phosphate (15%). Plasma C-terminal telopeptide (CTX) was increased - 1.06 ng/ml (reference range: 0.1-0.5 ng/ml). Free deoxypyridinoline/creatinine ratio (fDPD/Cr) in urine was also increased - 20.2 (reference range: 2.3-5.4). In April 2004, this patient was prescribed disodium etidronate 400 mg day. Nearly 3 months after commencing therapy with etidronate, plasma CTX decreased to 0.87 ng/ml. fDPD/Cr in urine also decreased to 12.4. After 4 months of etidronate therapy, 24-h urinary calcium excretion had decreased to 6.1 mmol/day. CONCLUSION: Etidronate (400 mg daily) is a very effective inhibitor of calcium phosphate crystallisation. Etidronate decreased urinary excretion of calcium, an important factor in prevention of calcium phosphate bladder stones. Etidronate therapy is not a substitute for other well-established methods for prevention of vesical calculi in spinal cord injury patients, for example, large fluid intake, avoiding long-term catheter drainage. Intermittent therapy with etidronate may be considered in selected patients, in whom hypercalciuria persists after instituting nonpharmacological therapy for an adequate period, for example, early mobilisation, weight-bearing exercises, and functional electrical stimulation. However, possible side effects of etidronate, and the fact that etidronate is not licensed in United Kingdom for prevention of urolithiasis, should be borne in mind.

Memokath (Engineers & Doctors A/S, Hornbaek, Denmark) a second generation urethral stent composed of titanium nickel alloy with shape memory effect was deployed in 10 male spinal cord injured patients with urinary retention. The stent was inserted under sterile conditions via a delivery catheter under fluoroscopic control in seven and with the aid of a flexible cytoscope in three. The proximal end of the stent was positioned at the bladder neck and 50 ml of normal saline at 45 degrees C was flushed through the stent which resulted in expansion of the distal most four coils of the stent in the proximal bulbar urethra; thus the internal sphincter (bladder neck) and external sphincter zone were kept open by the stent. Urethral stenting helped to achieve complete vesical emptying in all 10 patients. The complications included transient autonomic dysreflexia in two, transient urinary retention due to blood clot in one, and acute urinary tract infection in one patient. With a follow up of 3-7 months, all 10 patients have been asymptomatic, with residual urine of less than 50 ml. There has been no migration or blocking of the stent. However, these stents require replacement at 12-18 months, but it is a short procedure as the Memokath, when cooled with saline at 4 degrees C, becomes supersoft, enabling its easy and nontraumatic removal.(ABSTRACT TRUNCATED AT 250 WORDS)
