[Bladder dysfunction in patients with stages I-III of Parkinson's disease].

Objective: To evaluate bladder dysfunction (BD) and its relationship with Parkinson's disease (PD) symptoms and dopaminergic therapy.

Material And Methods: One hundred and thirteen patients with PD of I-III H&Y stages were examined using the following scales: IPSS, including irritative and obstructive symptom indices, UPDRS I-IV, Sch&En, PDQ-39, BDI, STAI, PFS-16, GDSS, GSRS, MMSE, FAB and NMSQ.

Results: Most of the patients (89.

[Therapeutic and diagnostic classification of degenerative spondylolisthesis: validation and multiple-center inter-observer agreement].

Object: To evaluate inter- and intra-observer agreement of the proposed diagnostic and treatment classification of degenerative spondylolisthesis.

Material And Methods: The proposed diagnostic and treatment classification of degenerative spondylolisthesis was validated according to the GRRAS protocol. For this purpose, we retrospectively analyzed MRI, CT and spinal radiography data in 20 patients.
