NBSS, Qualiveen and SF-Qualiveen questionnaires will be administered to participants.

NBSS, Qualiveen and SF-Qualiveen questionnaires will be administered to participants.

NBSS, Qualiveen and SF-Qualiveen are self-reported questionnaires.

The ICIQ-SF questionnaire is a brief questionnaire that was devised to assess the burden of urinary incontinence in a patient's life, evaluating its impact on patients' QoL. It is composed by four questions that evaluate frequency, severity, and impact of incontinence on QoL and another section evaluating usual urinary loss situations. The minimum and maximum values range between 0-21 points. Higher the score, the greater the severity of the symptoms.

The ICIQ-SF has been chosen as the validation questionnaire.

Neurogenic Bladder Symptom Score Questionnaire is a 24 item self-reported questionnaire (0-74 points). The questionnaire includes 4 subgroups; incontinence (0-29 points), storage&voiding (0-22 points) and consequences (0-23 points). Higher the score, the greater the severity of the symptoms.

The Qualiveen is divided in two major sections-Specific Impact of Urinary Problems on Quality of Life (SIUP) and General Quality of Life (GQoL).

The first part, specific for urinary problems, has a total of 30 questions and is divided in four domains: inconvenience, restrictions, fears, and impact on daily life (9, 8, 8, and 5 questions, respectively).

Each answer has five quantified items on a five category ordinal Likert scale with values ranging from 0 (no impact) to 4 (greatest negative impact). The average for each domain is calculated and used to obtain the final SIUP score (average of all domains, range from 0 to 4, 4 being the greatest negative impact).

The second section, GQoL, has nine questions, also with a five-category ordinal Likert scale. It ranges from Very badly to Very well, with values ranging from -2 to +2, respectively.

Final general QoL value is calculated as the average for the nine questions, also ranging from -2 to +2.

The SF-Qualiveen is a validated short version of the Qualiveen questionnaire and evaluates urinary-specific quality of life. The SF-Qualiveen consists of eight questions and reports on four domains of two questions each: bother with limitations, fears, feelings, and frequency of limitations. Responses are given on a 5-point Likert like scale, where a score of 0 indicates "no impact" and 4 "high impact." The SF-Qualiveen total score is calculated as the mean of the eight responses and the domain scores are calculated as the mean score of the responses per domain.
