   Case Report Top

A 50-year-old male presented with a history of recur­rent graveluria since the age of 38 years. He used to have dysuria and irritative voiding symptoms at the time of graveluria but without flank pain. One month before ad­mission he had acute retention of urine and was catheter­ised. On examination he had asymmetric limbs. Left upper limb was 3 cm and lower limb was 12 cm longer than opposite limb (Figure 1]. Intravenous urography revealed bilateral nephrocalcinosis, multiple renal and vesical cal­culi, papillary blush and precalyceal cystic spaces filled with contrast suggestive of medullary sponge kidney [Figure - 2]. Cystolithotripsy was done. Qualitative stone analy­sis revealed calcium, oxalate and phosphate. Patient was started on hydrochlorthiazide to reduce the risk of stone formation.

Medullary sponge kidney is a congenital benign disor­der of kidney consisting of diffuse ectasia or cystic dilata­tion of collecting ducts within medullary pyramid of one or both kidneys. Its incidence in general population has been estimated to be between 1 in 5,000 and l in 20,000. [1] Congenital hemihypertrophy is a rare condition of un­known aetiology with an incidence of 1 in 86,000. [2] It has been associated with variety of benign and malignant ab­dominal disorders. [3] The association of medullary sponge kidney with congenital hemihypertrophy was first reported in 1964. Since then only 30 cases have been documented in literature. Harris RE et al [4] reviewed 24 cases of medul­lary sponge kidney and congenital hemihypertrophy re­ported till 1981 and thereafter 6 more cases have been reported. Medullary sponge kidney is also found in asso­ciation with  Beckwith-Wiedemann syndrome More Details particularly if congenital hemihypertrophy is a part of syndrome. Although it has been proposed that the combination of med­ullary sponge kidney and congenital hemihypertrophy is a minor form of Beckwith-Wiedemann syndrome, our case did not have any other feature of Beckwith-Wiedemann syndrome.
