Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls) matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001), anxiety trait (P = 0.005) and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62). The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002) and depression (P < 0.001) and the number of recurrent colic episodes (anxiety-state: P = 0.016 and anxiety-trait: P < 0.001). These data suggest an association between recurrent renal colic and symptoms of both anxiety and depression.

Stressful life events were significantly greater among cases than controls.

Background: Quality of life (QoL) has not been a priority goal for patients with recurrent painful colic of renal lithiasis. Aim: To evaluate QoL in patients with recurrent painful symptoms due to renal colic. Methods: In this case-control study, 194 subjects (97 cases/97 controls) were matched according to age and gender. Cases were patients at an outpatient clinic with a confirmed diagnosis of nephrolithiasis with recurrent painful renal colic. The control group consisted of patients seen at an ophthalmology outpatient clinic for refraction symptoms. Main outcome measures: QoL was measured using the SF-36. Results: Average SF-36 dimension scores for cases and controls, respectively, were: physical function 70/95, role-emotional function 33.3/100, role limitations due to physical problems 25/100, bodily pain 41/84, general health status 52/82, vitality 45/80, social function 62.5/100 and mental health 52/84. All values were statistically different (p < 0.001). Using multiple linear regression, there was a statistically significant QoL drop in subjects with lithiasis. Low social and economic levels were associated with the following SF-36 domains: physical function, general health status, vitality and mental health. The influence of the diagnosis on role-physical and role-emotional domains. Analysis of the physical and mental components of the SF-36 Scale showed significantly lower averages between cases and controls: PCS (p < 0.001) and MCS (p < 0.001). Conclusion: The QoL of patients with painful recurrent symptoms due to renal colic was substantially impaired.

A significant difference was observed between the groups regarding the question on the practicing of sports. For this question, 29/33 healthy children reported to be very satisfied, while only 17/33 out of the ESRD group stated likewise. When asked about satisfaction of the children at the table with the family, 23/33 of the controls and 16/33 of the ESRD group reported to be very satisfied, showing a trend toward a significant difference (P = 0.059). No differences were observed for the remaining questions. We conclude that ESRD was linked to lower perception of quality of life in leisure aspects (sports) and a trend regarding functional issues (meal at the table).
