Factors Affecting Kidney Function and Stone Recurrence Rate After Percutaneous Nephrolithotomy for Staghorn Calculi: Outcomes of a Long-Term Followup

Abstract

In almost 80% of patients with staghorn stones renal function was improved or maintained after percutaneous nephrolithotomy, as documented during long-term followup. Stones recurred in a third of the patients with staghorn calculi.

The outcome of percutaneous nephrolithotomy on ≥50 mm staghorn and multiple calyceal stones

“…[1] In a study by Akman et al [4] a total of 77 complications were observed in 64 patients. The most frequently seen complication was bleeding, and angioembolization was performed in 2 out of 47 patients because of development of pseudoaneurysm, and arteriovenous fistula.…”

“…[6] Increased number or dimensions of stones bring with them more frequent interventions, Kaya et al The outcome of percutaneous nephrolithotomy on ≥50 mm staghorn and multiple calyceal stones higher number of complications, and lower stone-free rates. In a study by Akman et al [4] PNL was performed on 272 renal units because of the presence of staghorn kidney stone, and median stone-free rate at a single session was reported as 76.5%. More than one accesses were made into 102 (37.5%) units, while only a single access was made for 170 (62.5%) units.…”

“…In a study,m ESWL was performed for 29 patients after PNL, 3 patients received recurrent PNL, and another 3 patients underwent ureterorenoscopy. [4] As additional treatments El Nahas et al [7] performed PNL in 30%, ESWL in 17%, and as previously unplanned treatment they used DJ implantation, ureteroscopy, and open surgery in 10.4% of their patients. In our study we performed ESWL in 5, and F-URS in 6 patients with residual kidney stones.…”

“…As the number of access sites increases, complication rates, and especially risk of bleeding also increase. [4] In recent years, decrease in the complication rates has been reported with the use of small sized access instruments.…”

Review on renal recovery after anatrophic nephrolithotomy: Are we really healing our patients?

“…Several studies have assessed the impact of PNL on renal function [25][26][27][28][29][30][31][32] . Usually there is an immediate decrease on renal function after surgery with return to baseline on long term.…”
