Purpose:
To systematically review the use of suction/vacuum-assisted retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PCNL) in children/adolescents with kidney stones.
Methods:
The PICOS model (Patient Intervention Comparison Outcome Study type) was used to frame and answer the clinical question; P: children and adolescent men with kidney stones; I: use of suction during PCNL or RIRS; C: no suction devices or none; O: complications and stone-free rate (SFR); S: prospective and retrospective studies; case reports. The literature search was performed on 14th May 2024 using Embase, PubMed, and Scopus. Only English papers were accepted.
Results:
Ten articles were included. There were 9 papers on mini-PCNL and the remaining one compared mini-PCNL with RIRS. PCNL studies found excellent SFR (73-100%) with zero transfusion rate and a low rate of infectious complications (fever up to 9.6% and sepsis rate of 1%). Among these studies, there was a case report on the use of shock pulse lithotripter with complete stone clearance.
Conclusions:
Our review shows that there is little data on the use of suction/vacuum-assisted mini-PCNL/RIRS in kidney stone children/adolescents. However, these preliminary data demonstrated that vacuum-assisted mini-PCNL had excellent SFR with a low rate of complications.
