- The influence of interstitial cells of Cajal density in the outcomes of pyeloplasty in adults: A prospective analysis(2023) SROUGI, Victor; BANDEIRA, Rodolfo Anisio Santana de Torres; REIS, Sabrina Thalita; SANTOS, Gabriel Arantes dos; ANDRADE, Hiury da Silva; LEITE, Katia Ramos Moreira; HAMILTON-CHO, David; MITRE, Anuar Ibrahim; ARAP, Marco Antonio; SROUGI, Miguel; DUARTE, Ricardo JordaoPurpose: To evaluate if the density of interstitial cells of Cajal (ICC) in the ureteropelvic junction (UPJ) influences the outcomes of pyeloplasty in adults. Methods: Twenty-three patients with the diagnosis of ureteropelvic junction obstruction (UPJO) that underwent laparoscopic dismembered pyeloplasty were included. ICC density was measured using immunohistochemistry reaction for c-KIT expression in the resected UPJ segment. Pyeloplasty outcome was evaluated by patient self-report pain, urinary outflow using DTPA renogram and hydronephrosis assessment using ultrasound (US) at 12 months of follow-up. A logistic regression analysis was performed to assess the association of pyeloplasty outcomes and ICC density. Results: Low, moderate, and high ICC density were present in 17.4%, 30.4%, and 52.2% of the patients, respectively. Complete pain resolution was observed in 100%, 85.7%, and 75% of patients with low, moderate and high ICC density, respectively (p = 0.791). DTPA renogram improved in 75%, 85.7%, and 91.7% of patients with low, moderate and high ICC density, respectively (p = 0.739). Hydronephrosis improved in 25%, 85.7%, and 91.7% of patients with low, moderate and high ICC density, respectively (p = 0.032). Conclusions: Patients with high ICC density have a significant amelioration of hydronephrosis after pyeloplasty. However, ICC density is not associated with functional outcomes.
- Laparoscopic Kidney Denervation for Refractory Loin Pain: Can We Predict Outcomes?(2016) SROUGI, Victor; DUARTE, Ricardo J.; SROUGI, Miguel; YU, LuisA 19-year-old female patient presented refractory disabling loin pain associated with mild kidney atrophy (split renal function of 33%). Investigation revealed elevated serum renin level; a therapeutic test with oral renin inhibitor was tried, obtaining important pain control. Aiming to resolve the symptom while preserving the patient kidney and attributing the pain mechanism to be associated with the abnormal renin production, a laparoscopic kidney denervation was performed with no complications and complete pain resolution.

- Pediatric genitourinary oncology(2013) DENES, Francisco Tibor; DUARTE, Ricardo Jordao; CRISTOFANI, Lilian Maria; LOPES, Roberto IglesiasTumors of the kidney, bladder, prostate, testis, and adrenal represent a large part of the adult urologic practice, but are relatively infrequent in children. The natural history and management of these tumors in the pediatric age is different from that of the adults. As result of the successful work of several clinical trial groups in recent decades, there has been a significant improvement in their cure rates. The aim of this article is to review their most significant clinical aspects, as well as to present an update in their management.
