To provide a review of 3 nephrometry scoring systems and case examples with nephrometry scoring and clinical implications.


Topic Review

Renal malignancy is a frequent clinical scenario, with a relative stable mortality since 1990s, though increasing incidence [1-3]. Renal cell carcinoma is the most common solid renal lesion accounting for approximately 90% of all kidney malignancies [3]. The standard of care for localized renal malignancies is surgical excision and in the last 2 decades nephron-sparing partial nephrectomy have emerged as a viable alternative to radical excision in an increasing number of localized disease cases (T1-T2), with laparoscopic partial nephrectomy considered the gold standard of treatment for localized disease [3].

 

In comparison with radical nephrectomy, partial nephrectomy is more technically challenging and can lead to more complications post-operatively, especially in complex tumours. Nephrometry scores aim to use predictive/reproducible characteristics of localized...

Conclusions

In conclusion, nephrometry scoring systems provide a method to stratify the complexity of renal tumours, with implications for surgical planning, that has been mostly adopted by urologists but are less familiar to radiologists.
