**# Quality of the contralateral kidney and its implications for compensatory hypertrophy
**# Quality of the contralateral kidney and its implications for compensatory hypertrophy
**#* Compensatory hypertrophy of the contralateral kidney will magnify the perceived impact of infection on renal growth because the contralateral developing kidney will assume the required renal function whenever the ipsilateral kidney is unable to contribute optimally to function.
