Detection of bladder cancer with feature fusion, transfer learning and CapsNets
Freitas, Nuno Renato Azevedo; Vieira, Pedro Miguel; Cordeiro, Agostinho; Tinoco, Catarina; Morais, Nuno; Torres, João Nuno Braga PimentelThis paper confronts two approaches to classify bladder lesions shown in white light cystoscopy images when using small datasets: the classical one, where handcrafted-based features feed pattern recognition systems and the modern deep learning-based (DL) approach. In between, there are alternative DL models that had not received wide attention from the scientific community, even though they can be more appropri...
Step by step illustrative video of laparoscopic artificial urinary sphincter im...
Cordeiro, Agostinho; Torres, João Nuno Braga Pimentel; Nogueira, Vitor H.; Lima, Estêvão Augusto Rodrigues de[Excerpt] Stress urinary incontinence (SUI) is the most common subtype of incontinence and is defined as the perception of urine loss with effort. In most cases, it is due to insufficient support of the bladder neck, urethral hypermobility, and in a minority of cases, intrinsic sphincter deficiency (ISD). Sometimes both pathophysiological mechanisms occur simultaneously.[...]
Comparative Study of the Efficacy and Safety Between Two Bipolar Instruments (E...
Cordeiro, Agostinho; Conde, Mariana; Torres, João; Morais, Nuno; Mota, Paulo; Rocha, Ana; Grimaldi, Giovanni; Botelho, Francisco; Nogueira, Vitor H.Introduction: Hemostasis is a central issue in laparoscopic surgery. There are no clear guidelines when it comes to the choice of what energy scissor to use. This study compares the efficiency and security between EnSeal® and LigasureTM in the sealing of arteries and veins in an ex-vivo porcine model. Methods: The instruments were compared with each other with respect to cutting speed and burst pressure (BP) af...
Accuracy and Safety of Percutaneous Core Biopsy in Management of Renal Masses: ...
Mota, Paulo; Torres, João; Morais, Nuno; Cordeiro, Agostinho; Carvalho-Dias, Emanuel; Botelho, Francisco; Oliveira, Carlos; Cerqueira-Alves, MárioIntroduction: The characterization of renal masses by biopsy before a surgical procedure is currently an option. Without this prior characterization, patients with benign renal masses may be likely to undergo unnecessary surgeries. The purpose was to determine the diagnostic accuracy and safety of renal mass biopsy. Material and Methods: Prospective uni-institutional study of 38 patients submitted to renal mass...
Smoking Cessation after Bladder Cancer Diagnosis
Mota, Paulo; Sousa, Pedro Miguel; Botelho, Francisco; Dias, Emanuel Carvalho; Cordeiro, Agostinho; Torres, João Pimentel; Morais, Nuno; Anacleto, SaraSmoking is an important risk factor for the development, recurrence and progression of bladder cancer. Our aim was to analyze smoking habits after diagnosis in bladder cancer patients. Additionally, we evaluated patient knowledge about smoking as a risk factor and the urologist role in promoting abstinence.

Extraperitoneal Video-Assisted Simple Prostatectomy: A Surgery for Beginners?
Mota, Paulo; Carvalho, Nuno; Dias, Emanuel Carvalho; Cordeiro, Agostinho; Torres, João Nuno Braga Pimentel; Morais, Nuno; Cerqueira-Alves, MárioIntroduction and Objectives: Laparoscopic simple prostatectomy has been introduced with the purpose of reducing the morbidity or the classical and standard open surgeries. The extraperitoneal (préperitoneal) or preperitoneal approach adds no technical difficulty and additionally allows no surgical violation of the peritoneum. The purpose of this work (video) is to show a step-by-step video of the simple extrape...
Surgical Treatment of Ureteral Stenosis in Urinary Diversions: Is Laparoscopy a...
Mota, Paulo; Carvalho, Nuno; Dias, Emanuel Carvalho; Cordeiro, Agostinho; Torres, João Nuno Braga Pimentel; Morais, NunoIntroduction: Radical cystectomy is the gold-standard treatment for urothelial and muscle invasive bladder cancer. Morbidity is high for this procedure, and ureteral stenosis with consequent renal damage is a possible complication for all types of urinary diversions. The endoscopic approach is a therapeutic option although it is not very effective. Open surgery is more effective, but is associated with signific...
Ileal intussusception due to a parasite egg : a case report
Pinto, José Pedro; Cordeiro, Agostinho; Ferreira, Ana Margarida; Ferreira, Ana Margarida; Antunes, Conçeição; Botelho, Patrícia; Rodrigues, Ana JoãoIleal intussusception is the invagination of the small intestine within itself and accounts for 1% of cases of acute obstruction. However, physicians do not initially consider intussusception as a possible diagnosis of obstruction due to its rarity in adults. Herein, we report the case of a 22-year-old male who was admitted to the Emergency Department with continuous abdominal pain. Ultrasonography and computed...
