PCNL in horseshoe kidney- the first experience at HUSM

Horseshoe kidney is one of the commonest congenital renal fusion anomalies with an incidence of 0.25% in general population. Disturbances in urine flow, drainage and concomitant infections promote stone formation is common. Percutaneous nephrolithotripsy (PCNL) in horseshoe kidney is a challenge due to its anatomical difference and thus a modified technique is needed. Hereby, we report our first experience with PCNL in this anomaly, a 55 year old with left staghorn renal calculi in a horseshoe kidne

High-flow priapism in a 12-year-old boy: Role of super-selective embolization

Priapism is caused by an imbalance between penile blood inflow and outflow. There are two types, low flow priapism due to venous occlusion and high flow priapism due to uncontrolled arterial flow to the veins. High flow priapism most frequently occurs as a result of penile trauma where the intercavernosal artery discruption causes an arteriocavernosal fistula. It is rarely encountered in the pediatric and pre-pubertal population. Clinically it manifests as a painless, prolonged erection after perineal trauma. Treatment has ranged from expectant management to open surgical exploration with vessel ligation. We report the successful treatment of high flow priapism in a 12 year old pre-pubertal boy with superselective embolisatio

Seasonal and vertical distribution of macrofoulants in Kalpakkam coastal waters

270-275Vertical distribution and community succession of macrofoulants were studied in the coastal waters of Kalpakkam for 1 y. Studies were made with teak wood panels of 15 cm x 10 cm. For short-team series, panels were suspended at 1,3,5 and 7 m depths. Long-term panels were all suspended at 1 m depth. Fouling organisms observed were barnacles, ascidians, hydroids, polychaetes, bryozoans and mussels. Considerable faunistic and biomass variations were observed both with respect to season and depth. Biomass value was maximum in October at 5 m depth and minimum in February at 3 m depth. Barnacles were the most dominant group and were found occurring almost throughout the year. However, green mussels, a dominant group in MAPS subterranean tunnel, were absent on the experimental panels. Dominant community observed was either ascidians or barnacles. Patterns of ecological succession observed during different periods of the year were not significantly different
