The authors compared the utility of the International Prostate Symptom Score IPSS and Japan Orthopaedic Association JOA score for evaluating lower urinary tract symptoms LUTS associated with lumbar degenerative diseases. A total of 178 patients with lumbar degenerative diseases were assessed according to the IPSS and JOA score. These included 32 females F group , 80 males without urinary tract lesions Mn group , and 66 males with urinary tract lesions Mu group. Patients with 8 points on the IPSS and 3 points on the JOA score were classified as LUTS. Additionally, we investigated both storage and voiding symptoms using IPSS. Patients with 4 points from a possible maximum of 15 across 3 questions relating to storage and voiding symptoms on the IPSS were defined as symptom. Among all 178 patients, LUTS positivity was detected in 85 patients 48 by the IPSS and in 81 patients 46 by the JOA score. In the F group, 10 patients 31 were LUTS on both scoring systems. In the Mn group, 33 41 and 39 patients 49 were LUTS on the IPSS and JOA score, respectively. Thus, there was good statistical correlation between the IPSS and JOA score. However, a more detailed analysis of the findings revealed that the group defined as normal by JOA score had worse symptoms on the IPSS 25 of the 178 patients, including 14 in the F group and 22 in the Mn group. Moreover, IPSS clearly identified many cases with storage symptoms and many mixed cases with both voiding and storage symptoms associated with lumbar degenerative disease. In conclusion, IPSS was considered to be a more sensitive and useful scoring system than the JOA score for evaluating LUTS associated with lumbar degenerative diseases.
The authors compared the utility of the International Prostate Symptom Score IPSS and the Japan Orthopaedic Association JOA score for evaluating lower urinary tract symptoms LUTS associated with cervical degenerative myelopathy.A total of 128 patients with cervical degenerative myelopathy were assessed according to the IPSS and JOA score. These included 31 females F group , 61 males without urinary tract lesions Mn group , and 36 males with urinary tract lesions Mu group . Patients with 8 points on the IPSS and 2 points on the JOA score were classified as LUTS . Additionally, we investigated both storage and voiding symptoms using the IPSS. Patients with 4 points from a possible maximum of 15 across 3 questions relating to storage and voiding symptoms on the IPSS were defined as symptom . Among all 128 patients, LUTS positivity was detected in 58 patients 45by the IPSS and in 52 patients 41 by the JOA score. In the F group, 13 42 and 10 patients 32 were LUTS based on the IPSS and JOA score, respectively. In the Mn group, 23 38 and 20 patients 33 were LUTS based on the IPSS and JOA score, respectively. Thus, there was good correlation between the IPSS and JOA score.However, a more detailed analysis of the findings revealed that the group defined as normal by the JOA score had worse symptoms on the IPSS 24 of the 128 patients, including 24 in the F group and 22 in the Mn group. In addition, it was revealed that the group defined as slight by the JOA score had a wide range of symptoms from 2 to 27 on the IPSS. Moreover, a significant difference was not observed in IPSS between the slight group and severe groups according to the JOA score.Also from another viewpoint, IPSS clearly identified many cases with voiding symptoms and many mixed cases with both voiding and storage symptoms associated with cervical degenerative myelopathy.In conclusion, IPSS was considered to be a more sensitive and useful scoring system than the JOA score for evaluating LUTS associated with cervical degenerative myelopathy.Received April 12, 2013 accepted June 26, 2013Key words international prostate symptom score IPSS , neurogenic bladder, lower urinary tract symptoms LUTS , cervical degenerative myelopathy, spinal cord diseases Jpn J Neurosurg Tokyo 23 241 247, 2014
