[Clinical characteristics of urinary system symptoms in 11 patients with neuronal intranuclear inclusion disease].

Abstract

To summarize the characteristics of urinary system symptoms in 11 patients with neuronal intranuclear inclusion disease (NIID), in order to improve the understanding of the disease. A retrospective analysis was performed on 15 patients with NIID of the First Affiliated Hospital of Zhengzhou University, which were enrolled between January, 2020 and December, 2022. All of them were confirmed by NOTCH2NLC gene and pathology. GGC repeated expansion mutationof NOTCH2NLC gene, the pathogenic gene of NIID, was detected by gene test, and eosinophilic intranuclear inclusions were detected by skin pathological biopsy. 4/15 patients started with urinary symptoms, 11/15 patients with NIID combined with different degrees of urinary system symptoms, manifested as frequent urination, weak urination, incontinence and other neurogenic bladder symptoms, and the serious patients due to long-term urinary retention, secondary ureteral dilation, hydronephrosis, even renal failure, some patients with urinary system symptoms may be earlier than other systems.
