Evaluation and comparison of S.T.O.N.E. and Guy's scoring systems for predicting percutaneous nephrolithotomy outcomes in supine position.

BACKGROUND: Percutaneous nephrolithotomy (PCNL) was applied in the prone position until recently. But also, in recent years supine positions was applied in patients with kidney stones. Predicting how much renal stones can be cleared after surgery and possibility of complications is an important question for both surgeons and patients. Therefore different scoring systems are used to evaluate outcomes of PCNL before surgery. PATIENTS AND METHODS: Between 2018 and 2020, 80 patients with renal stone who underwent PCNL in the supine position were evaluated preoperatively by S.T.O.N.E. and Guy's scoring systems (GSS). The predictions of both scoring systems for stone-free and complication rates in patients who underwent PCNL in the supine position were evaluated. Also, these scoring systems were compared among themselves for reliability. RESULT: In both scoring systems, there was a statistically significant difference between postoperative stone-free (SF) and residual stone (RS) of patients and in predicting the likelihood of complications in patients. No statistically significant difference was found between the two scoring systems in predicting the stone-free rate. CONCLUSION: Our findings revealed that S.T.O.N.E. nephrolithometry and Guy's score systems can be used effectively to predict stone-free rate, complications, and operation duration in supine position PCNL for renal stones.

Evaluation of the relationship between compliance with the follow-up and treatment protocol and health literacy in bladder tumor patients.

Objective: To investigate the relationship between the compliance of bladder cancer patients with cystoscopic follow-up and the treatment protocol, and their health literacy. Methods: Patients who underwent transurethral resection surgery for bladder tumor were found to have non-muscular invasive bladder carcinoma on pathology examination and then underwent cystoscopic follow-up for 1 year or more were included in the study. Cystoscopic follow-up was recommended to the low- and high-risk groups in terms of progression and recurrence. The patients were evaluated with the Health Literacy Survey-European Union scale. Results: The mean age of the patients was 67.13 ± 10.77 years. The treatment continuity rate was 80.50% (n = 33) in the adequate health literacy group (n = 41) and significantly higher than the 56.50% (n = 48) rate in the inadequate health literacy group (n = 85) (p = .008). The health literacy results revealed that the health promotion and general index score was higher in the group of patients under the age of 65. Conclusions: Adequate health literacy in bladder cancer patients is associated with better compliance with the treatment protocol. Young patients show better compliance with the follow-up protocol recommended by the physician. Increasing the follow-up protocol compliance of elderly patients with inadequate health literacy is necessary.
