OBJECTIVE: To prospectively compare the Guy's Stone Score (GSS), S.T.O.N.E. [stone size (S), tract length (T), obstruction (O), number of involved calices (N), and essence or stone density (E)] score and the Clinical Research Office of the Endourological Society (CROES) nephrolithometric nomogram to predict percutaneous nephrolithotomy (PCNL) success rate and assess the correlation with perioperative complications. PATIENTS AND METHODS: We prospectively evaluated all consecutive PCNL patients at our institute between 1 November 2013 and 31 May 2015. The above scoring systems were applied to preoperative non-contrast computed tomography and the practical difficulties in such applications were noted. Perioperative complications and the stone-free rate (SFR) were also recorded. Receiver operating characteristic curves were drawn and the areas under curves were compared and appropriate statistical analysis done. RESULTS: In all, 48 renal units were included in the study. The overall SFR was 62.2%. The presence of staghorn stones (ß = 27.285, 95% confidence interval 1.19-625.35; P = 0.039) was the only significant variable associated with the residual stones on multivariate analysis. Stone-free patients had significantly lower median GSS (2 vs 4) and S.T.O.N.E. scores (6 vs 10) and higher median CROES scores (83% vs 63%) (all P < 0.001) compared to residual-stone patients. All scoring systems were significantly associated with SFR (all P < 0.001). There was no significant difference in the areas under curves of the scoring systems (0.858, 0.923, and 0.931, respectively). Furthermore, all scoring systems had weak correlations with Clavien-Dindo classified complications (r = 0.29, P = 0.045; r = 0.40, P = 0.005 and r = -0.295, P = 0.04, respectively). We found no standardisation for the measurement of stone dimensions, tract length, Hounsfield units, and staghorn definition. CONCLUSIONS: All scoring systems equally predicted SFR and had a weak correlation with Clavien-Dindo complications. Standardisation is needed for the variables in which they have been found deficient.

Developmental anomalies of the urogenital tract are rare but often encountered. Zinner's syndrome is a rare congenital abnormality of mesonephric (Wolffian) duct consisting of unilateral renal agenesis, ipsilateral seminal vesicle cyst, and ipsilateral ejaculatory duct obstruction due to developmental arrest in early embryogenesis affecting the caudal end of Mullerian duct and only approximately a 100 cases have been reported so far. Radiologic modalities such as intravenous pyelography, ultrasonography, vasovesiculography, contrast enhanced computed tomography, and magnetic resonance imaging are all helpful in diagnosis of this unusual entity. We present here an extremely rare developmental anomaly involving the Mullerian ducts, which would remain undiagnosed but for radiologic imaging. The patient presented with symptoms of lower urinary tract irritation.

Herlyn-Werner-Wunderlich (HWW) syndrome is a very rare congenital anomaly of the urogenital tract resulting from maldevelopment of both Mullerian and Wolffian ducts. It is characterized by the triad of uterus didelphys, obstructed hemivagina and ipsilateral renal agenesis. It generally presents at puberty shortly following menarche with the symptom of acute pelvic pain. Management of these cases is surgical and consists mainly of vaginoplasty with excision of the vaginal septum in order to release the obstruction and prevent the long term complication of recurrent pyocolpos and infertility. We report here a case of Herlyn-Werner-Wunderlich syndrome in a 13-year-old adolescent girl, emphasizing the role of imaging in the accurate and prompt diagnosis of this rare developmental urogenital anomaly. Only a few hundred such cases have been reported in literature till date.

Ewing's sarcoma is a common malignant bone tumour presenting in children and young adults. Rarely extra- skeletal soft tissues and visceral organs can also be the site of origin of Ewing's sarcoma. Primary pulmonary Ewing's sarcoma is an extremely rare malignancy which occurs in the paediatric population. We report an unusual case of primary pulmonary Ewing's sarcoma in a nine year old girl who presented with features of superior vena cava syndrome in the emergency department. The diagnosis was confirmed pathologically both by light microscopy and immunohistochemistry. The patient was put on chemotherapy and surgery was planned but the patient expired within three days of starting chemotherapy.

Leiomyomas are benign tumours of smooth muscle origin and are the most common uterine masses in females of reproductive age group. Extrauterine leiomyomas are also encountered occassionally and most commonly they involve the genitourinary tract. Leiomyomas arising from urethral smooth muscle are exceptionally unusual which can pose a diagnostic dilemma. Patients usually present with urinary complaints and an intraluminal soft tissue mass bulging from urethral meatus. We are presenting the imaging findings of leiomyoma of distal urethra presenting as a perineal mass with histopathological correlation.

Marchiafava-Bignami disease (MBD), a rare disorder most commonly seen in patients with a history of alcohol consumption, involves progressive demyelination and subsequent necrosis of the corpus callosum. Because clinical signs are nonspecific, the role of computed tomography and magnetic resonance imaging is essential to confirm the diagnosis. Early diagnosis with imaging and prompt treatment may improve the prognosis of MBD.
