[Measuring the degree of patient satisfaction treated at an extracorporeal lithotripsy unit]

To determine by questionnaires the level of satisfaction of patients diagnosed of urinary lithiasis treated by extracorporeal shock wave lithotripsy (ESWL) in our Renal Stone Centre.

A total of 100 patients with urinary lithiasis who underwent ESWL, 54 males and 46 females with an average age of 50 years, answered a Lickert type questionnaire (score 1 to 5) consisting of 6 questions to evaluate the patient satisfaction regarding the treatment received. The relationship between answers to each question and patient's clinical characteristics were analyzed applying chi-square and linear regression to determine the level of significance of these relationships.

General satisfaction level was high, with a mean score of 4.33 for the six questions. The most valued question was the one referred to assistance received in relation to the planned medical one. Questions referred to treatment suitability, expected timing, and absence of complexity were also highly valued. The least valued question was the one referred to pain level during treatment, which level was kept in a good approval degree with a mean score of 3.81 despite the fact that some patients said they suffered more pain than expected.

ESWL resulted in a high level of satisfaction among patients treated for urinary lithiasis, revealed not only by its suitability, easy planning and performance, but also by its low level of complexity. Pain experienced by these patients during treatment was well-tolerated, so that general use of anesthesia was not required.
