defect securely. Care should be taken to avoid excluding the calyx or including segmental arteries in the
suturing process. In this chapter, we emphasized the substantial changes of suturing techniques on the
kidney over the years in partial nephrectomy. The emphasis has been on emulating principles from open
surgery, streamlining procedures, and safeguarding renal parenchyma. Running sutures, particularly those
using barbed wires, have shown promise in reducing operating time and ischemia duration. Although no
definitive evidence and recommendations are provided in this context, the surgeon’s experience is still of
utmost importance.

Future studies incorporating standardized reporting of resection and reconstruction techniques are essential
to evaluate their influence on short-term and long-term functional outcomes. Techniques that shorten
clamping time may benefit long-term renal function and should be explored further through additional
research, although they may be harmful in non-high volume centers.
