Introduction Defecation and urination disorders are well known problems in children which leads their parents to consult a specialist. The solving of these problems usually needs a multidisciplinary approach and cooperation of different specialists to find a diagnosis and determine the correct treatment. Methods Abnormal pudendal nerve function was investigated with the St. Mark EMG electrode in six children between the ages of 8 and 13 years with pelvic organ disorders and preliminary diagnosis of neurogenic bladder (NB). The pudendal nerve terminal motor latency (PTL) was measured after the stimulation on both sides. Results In comparison with the literature normal values of 1.58 ± 0.33 ms (Sentovich, Stephen M., 1998) the PTL was increased in all patients to the mean value of 1.92 ± 0.33 ms. The increased PTL on one side (OS) was found in one patient and on both sides (BS) in five patients. In BS patients the increased PTL was accompanied by the ureteral hypoplasia and/or reduction of muscle tone tested by ultrasound investigation. In a one patient with OS, an increase in PTL was accompanied by clinical symptoms, there was no organic pathology. The increase in PTL exceeded the normal range by 0.9 ms. Conclusion The EMG study of the abnormal pudendal nerve function is important in diagnostics of urination disorders and possible pathogenesis in children. The preliminary data needs to be confirmed on a bigger cohort of patients.
