Predicting implantation with a neuromodulator using two different test stimulation techniques: A prospective randomized study in urge incontinent women.

AIMS: The purpose of this study was to determine whether a percutaneous needle electrode (PNE) technique or a surgical first stage lead placement (FSLP) better predicted whether a patient would progress to implantation of a pulse generator (IPG) in older urge incontinent women. METHODS: Thirty subjects > or =55 years with refractory urge incontinence who had been selected to undergo a test stimulation procedure were randomized to either PNE or FSLP. Thirteen underwent PNE placement and seventeen underwent FSLP placement. If during the test stimulation period subjects had greater than 50% improvement in their incontinence parameters they qualified for permanent lead and/or IPG implantation of the Interstim device. RESULTS: Twenty-one subjects (70%) responded to the test stimulation and underwent implantation, 15/17 (88%) in the FSLP group and 6/13 (46%) in the PNE group. Subjects who were randomized to the FSLP group were significantly more likely to proceed to implantation of the IPG (P = 0.02) than those in the PNE group. There was no significant difference in demographics, pre-test stimulation incontinence parameters or post-stimulation visual analog pain scores between the randomized groups or between test stimulation responders and non-responders. When comparing FSLP and PNE responders, there was no significant difference in the percent improvement in 24-hr pad weight, daily pad usage, or daily incontinence. CONCLUSION: FSLP better predicted progression to implantation of the IPG than a test stimulation with a PNE in an older urge incontinent cohort.

A statistical comparison of pad numbers versus pad weights in the quantification of urinary incontinence.

AIMS: Pad per day (PPD) usage is a frequently utilized measure of urinary incontinence. The 24-hour pad weight test (24PWT) is a reproducible test for quantifying incontinence volumes. We investigated whether PPD validly reports the magnitude of urinary incontinence. METHODS: This was a retrospective review of patients undergoing stress incontinence surgery from July 2002 to 2005. Inclusion criteria were a documented 24PWT and patient-reported PPD usage. Grams of urine loss per pad (GPP) provided a third measure of incontinence. Descriptive statistics and correlations between all variables and significance were noted. Factor analysis was performed on the three measures of leakage and age for all patients over age 50. RESULTS: One hundred forty-five male and 116 female patients met inclusion criteria. Correlated against 24PWT, GPP has the strongest association with a correlation of 0.80 for males and 0.88 for females. PPD has a weaker correlation of 0.64 for males and 0.61 for females (R2 = 0.38 overall). Factor analysis identified two components associated with incontinence. A "leakage" component correlated best with 24PWT and GPP. Additionally, an "age" component implies that despite stable 24PWT values, older patients increase GPP while PPD decreases. CONCLUSIONS: Self-reported PPD is an unreliable measure of incontinence as this variable only measures 38% of the variation of urinary incontinence volume. Patients at a given PPD level present with a wide range of 24PWT values. Older patients have higher per-pad leakage. Future incontinence studies should report 24PWT to ensure the most reliable and uniform data.

Renal calculi presenting as hyperhidrosis in patient with spinal cord injury.

Renal calculi in the spinal cord injury population present a diagnostic dilemma for urologists. However, 7% of all patients with spinal cord injury will develop renal calculi. Undiagnosed stone disease can lead to significant morbidity and mortality in this population. This case demonstrates the subtlety of the presenting symptoms of renal calculi in the patient with spinal cord injury.
