Experience of a Tertiary-Level Urology Center in the Clinical Urological Events of Rare and Very Rare Incidence. VI. Unusual Events in Urolithiasis: 1. Long-Standing Urethral Stones without Underlying Anatomical Abnormalities in Male Children

Objectives: The study aimed to present our center’s experience with long-standing urethral stones in male children with normal urethra. Materials and Methods: Retrospective search of our center data was done for the cases of long-standing urethral stones with normal urethra in male children during the period July 2001 – June 2016. Demographic and clinical data were studied. Results: Of more than 54,000 urolithiasis procedures, 17 male children (0.031%) were operated for long-standing urethral stones with normal urethra. In 14 cases (82.4%), residence was rural and parental education levels were low or none. All children were regularly prompted voiding with a history of difficulty or dysuria. All the stones lodged in the posterior urethra with an approximate mean duration of 2 months. The mean stone size of 11.29 ± 3.88 mm and rough surfaces in 88.2% of cases represented the main predisposing factors. Major complications included rectal prolapse in 1 case and vesicoureteral reflux in 3 cases. Endoscopic push-back was followed by disintegration in 76.5% or cystolithotomy in 17.7%, while it failed in 1 case that was treated by cystolithotomy. Conclusions: Long-standing urethral stones in male children with normal urethra are very rare misdiagnoses. Stone topography and sociocultural factors predisposed to their lodgments and negligence. Endoscopic treatment is the best approach.

Experience of a Tertiary-Level Urology Center in the Clinical Urological Events of Rare and Very Rare Incidence. III. Psychourological Events: 1. Psychic Anuria

Introduction: Psychic anuria is an old term, referring to a very rare psycho-urological event that has scarcely been studied so far. Materials and Methods: A retrospective study of the patients with psychic anuria presented to Assiut Urology and Nephrology Hospital during the period July 1991–June 2016 was done. Psychic anuria was defined, and the demographic and clinical characteristics including the methods of diagnosis and management were studied. Results: Of more than 3,800 cases of anuria, 9 female patients (0.24%) experienced psychic anuria in the age range of 17–43 years. Cardinal clinical findings included anuria for 36–72 h with absence of organic causes and normal renal function tests. Psychosocial risk factors were reported in the 9 cases. Anuria was documented by reliable history (56%) or observable urine collection (44%). Diagnosis was done by exclusion, where the investigations revealed no organic causes. Seven cases responded to the placebo intervention and 2 cases were self-limiting and resolved spontaneously. Conclusions: Psychic anuria is an extremely rare urological emergency that presents, mainly, in young adult females with unknown mechanisms. Renal vasoconstriction following psychosocial stressors is suggested. It is diagnosed by exclusion and resolves spontaneously or responds to placebo intervention as a mental distraction technique.

Isolated Renal Hydatid Cyst Misdiagnosed and Operated as a Cystic Renal Tumor

Objective: The aim of this work is the presentation of a case of isolated renal hydatid cyst with novel findings and an unusual surgical scenario. Clinical Presentation and Intervention: A 54-year-old female patient presented with left loin pain and a palpable left renal mass. Imaging described a well-demarcated left renal cystic lesion with a double-layer wall. Radical nephrectomy was performed due to the possibility of malignancy. On retrograde revision, the double-layer wall represented the detached germinative membrane of a hydatid cyst that was confirmed by histopathology. Conclusion: Isolated renal hydatid cyst could be misinterpreted as a renal tumor. It should be considered in the differential diagnosis of renal cystic lesions.

Introduction: Surgical fires are unique topics that belong to surgical never events and deserve urological attention. Materials and Methods: A retrospective search of our hospital records was done for the states of electrosurgical never events in the period from July 2001 to June 2016. The included events were classified according to the site of occurrence in relation to the patients body and possibilities of human involvement. The events were studied for the type, extent, damages, personnel involvements, complications, and management. Results: Of more than 82,000 urological interventions, 18 cases (0.022%) of electrosurgical never events were detected. Four subcategories were differentiated: electrosurgical theater fires (33.3%), electrosurgical contact skin burns (38.9%), electrosurgical internal injuries (16.7%), and electrocutions (11.1%). Electrosurgical theater fires included 3 ignition fires with fire skin burns and 3 device explosions. Fires only occurred with the use of alcoholic skin disinfectants. Contact skin burns resulted from inadvertent direct electrosurgical contacts, with 2 burns on the back, 3 burns on the lower limbs, 1 burn at the penile shaft, and 1 burn at the suprapubic region. Only 1 case of contact skin burn required plastic surgery. Electrosurgical internal in-juries involved the intestine, spleen, and urethra and were followed by major complications. Electrocutions involved a doctor and a patient with multiple bone fractures in the former. Conclusion: Urological electrosurgical never events are very rare incidents and were differentiated into 4 clinical subcategories. Human involvements varied from absence to major devastating complications. Reduction of these events depends on the adjusted use of electricity-based armamentarium.

Objective: Presentation of our centers experience in the management of intracorporeally-retained urological surgical items. Materials and Methods: Retrospective search of our centers data for cases of retained surgical items during the period July 2006 to June 2016. Each case was studied for the demographic and clinical variables including types, presentation, and management. Results: Out of more than 55,000 different urological interventions, only 39 cases (28 males and 11 females) had retained surgical items. Urolithiasis-related urological subspecialties were more involved than others. Forgotten items and technically-retained items occurred in 38.5 and 61.5% of cases, respectively, and were immediately discovered or discovered up to 10 years later. Material types were textiles, biosynthetics, and metallics in 31, 51, and 18%, respectively. Possible predisposing factors included complex surgeries, emergent intraoperative events, and extra approaches. Occurrences of retained surgical items before and after implemented corrective actions were 74.6 and 25.4%, respectively. All the final outcomes were either short- or long-term harm without deaths, organ losses, or permanent disabilities. Conclusion: Retained urological surgical items are surgical never events that result from forgetfulness or technical surgical human errors. Their sequels can be potentially fatal, but they are preventable and can be significantly reduced.

Experience of a Tertiary-Level Urology Center in the Clinical Urological Events of Rare and Very Rare Incidence. I. Surgical Never Events: 1. Urological Wrong-Surgery Catastrophes and Disabling Complications

Introduction: Surgical never events are preventable harmful non-intentional human errors. Urology is a common surgical specialty for their occurrence. Patients and Methods: A retrospective search of our centers data was done during the period 2006-2016 for surgical never events. Each included case was studied for the primary diagnosis, procedure, and subspecialty, never event type and timing, needed extra-interventions, urologist/procedure proportioning, outcomes, and possible underlying causes of the event. Results: Of more than 55,000 different urological interventions, 61 patients were involved in never events. Wrong procedures represented 75% of the never events, and endourology and urolithiasis subspecialties were more often involved. The main detectable underlying factor was the disproportion between the levels of the procedure class and the qualification of the urologist (41%). Thirty-four cases had extra-procedures. The short-term harm effect represented the final outcome in 42% of all events. Death, permanent organ loss, and long-term harm represented 20, 15, and 23%, respectively. Conclusion: Urological surgical never events are rare, but their final outcomes could be catastrophic, even leading to death.
