Introduction

It is known as "calcified ureteral catheter", one that cannot be removed by cystoscopy during the first attempt without the help of other auxiliary measures, due to encrustation or stone formation in it. They can occur in up to 13% of cases. The situation due to the COVID-19 pandemic favored the loss of follow-up of patients, which conditioned the presentation of calcified catheters in any degree, requiring an approach in multiple modalities.

Materials

Retrospective cohort study. We identified 15 patients who had one or two ureteral catheters placed between October 2019 and March 2021. All had some degree of catheter calcification according to the FECal classification. Surgical treatment performed, number of procedures, stone-free status, pre- and post-treatment glomerular filtration rate were reviewed. 15 patients with calcified JJ catheter, with a mean age of 46.6 years. The average time being JJ catheter carriers was 9.06 months.

Results

,

Endoscopic procedures were performed in 88.6%, 6.6% with laparoscopic procedure (due to renal atrophy) and 6.6% endoscopic + open procedure. Two patients required more than one procedure for its resolution. 100% of patients remain stone-free. The average glomerular filtration rate prior to JJ catheter placement was 75.9 mL/min/m2. The average post-treatment glomerular filtration rate was 80.56 ml/min/m2.

Conclusion

Despite the complications generated by the loss of follow-up due to the pandemic, it was possible to offer, to the majority, of patients with this condition a resolution of the underlying pathology and complication in a single surgical time, thus favoring a better short-term and even long-term results, functionally speaking.
