Updates on Wound Infiltration Use for Postoperative Pain Management: A Narrative Review.

Local anesthetic wound infiltration (WI) provides anesthesia for minor surgical procedures and improves postoperative analgesia as part of multimodal analgesia after general or regional anesthesia. Although pre-incisional block is preferable, in practice WI is usually done at the end of surgery. WI performed as a continuous modality reduces analgesics, prolongs the duration of analgesia, and enhances the patient's mobilization in some cases. WI benefits are documented in open abdominal surgeries (Caesarean section, colorectal surgery, abdominal hysterectomy, herniorrhaphy), laparoscopic cholecystectomy, oncological breast surgeries, laminectomy, hallux valgus surgery, and radical prostatectomy. Surgical site infiltration requires knowledge of anatomy and the pain origin for a procedure, systematic extensive infiltration of local anesthetic in various tissue planes under direct visualization before wound closure or subcutaneously along the incision. Because the incidence of local anesthetic systemic toxicity is 11% after subcutaneous WI, appropriate local anesthetic dosing is crucial. The risk of wound infection is related to the infection incidence after each particular surgery. For WI to fully meet patient and physician expectations, mastery of the technique, patient education, appropriate local anesthetic dosing and management of the surgical wound with "aseptic, non-touch" technique are needed.

Short ileal segment for orthotopic neobladder: a feasibility study.

OBJECTIVES: The objective of this study was to present the construction of a neobladder with a modified pouch technique using 25-35 cm of terminal ileum. METHODS: Thirty-eight patients whose pouch was constructed from 25-35 cm of terminal ileum (short pouch [SP] group) were prospectively evaluated vs 41 patients whose pouch was constructed from 50-70 cm of terminal ileum (long pouch group). Pouch volume, post-void residual (PVR) volume, need for catheterization, continence and voiding frequency were evaluated at 3 and 12 months after surgery. RESULTS: SP group patients had significantly smaller pouch capacity (440 vs 840 mL, P < 0.001) at month 12, and smaller PVR at postoperative months 3 (11 [0-43]vs 40 [0-147] mL, P < 0.001) and 12 (10 [0-90]vs 72 [0-570] mL, P < 0.001). SP group patients had significantly higher voiding frequency on postoperative month 3 (10 vs 9, P < 0.001) and 12 (7 vs 6, P < 0.005). Continence was significantly improved in the SP group compared with the long pouch group after 12 months (63.2% vs 34.1%, respectively, P = 0.034). Full continence improved significantly over time (P < 0.001) in the SP group, from 26.3% at month 3 to 63.2% at month 12. CONCLUSION: A pouch constructed from 25-35 cm of terminal ileum provides adequate capacity, smaller PVR, satisfactory continence and a better 24-h voiding frequency pattern during the first postoperative year.

Neobladder "Belgrade pouch": Metabolic consideration.

Background/Aim: The ileal neobladder should be a lowpressure reservoir with acceptable volume and relatively small resorptive surface. A larger inner surface of the ileal pouch is associated with the high resorption of urine metabolites through intestinal mucosa and systemic metabolic disturbances, while a too small pouch results in a higher frequency of voiding and incontinency. The aim of this study was to investigate it is possible to create a neobladder from a shorter ileal segment compared to standard surgical techniques, and reduce metabolic complications. Methods: This prospective study included 77 male patients, scheduled for radical cystectomy and orthotopic neobladder derivation. The patients were divided into two groups: the standard pouch (SP) group of 37 patients scheduled for standard orthotopic neobladder, using a 50−70 cm long terminal ileum segment; the "Belgrade pouch" (BP) group of 40 patients scheduled for original, orthotopic urinary reservoir, using a 25−35 cm long terminal ileum segment. We measured neobladder capacity, acidosis, base excess and bicarbonate concentration in the postoperative month 3rd, 6th, 12th and 15th. Results: At the end of the study, the patients from the SP group had much higher neobladder capacity than the natural bladder − 750 mL (range 514−2,050 mL); in contrast, the patients from the BP group had average capacity of 438 mL (range 205−653 mL) (p < 0.001). At the end of the study, there were more patients with acidosis (37.8% : 2.5%), base excess (35.1% : 7.5%) and low bicarbonate level (40.5% : 20.0%) in the SP group, than in the BP group, respectively (p < 0.001). Conclusion: "Belgrade pouch", make from 25−35 cm long terminal ileum segment may obtain adequate capacity and lower rate of metabolic disturbances than standard, high capacity orthotopic neobladders.

Pheochromocytoma of the urinary bladder--A case report.

INTRODUCTION: Pheochromocytoma of the urinary bladder is a rare tumor and presents less than 0.06% of all urinary bladder tumors. CASE REPORT: We presented a 49-year-old female patient with a history of daily paroxysmal hypertension accompanied with flushing of the face and upper chest, palpitations and excessive sweating prior to micturition. Ultrasonography reported a 3 cm bladder wall tumor. The 131I-metaiodobenzylguanidine (131I-MIBG) scan showed a pathological isotope accumulation in the projection of the bladder. The patient underwent a partial cystectomy. One year following the operation the patient was normotensive and without recurrence. CONCLUSION: The most efficient treatment option for bladder pheochromocytoma is surgical resection. The most important fact in the diagnostics is suspicion on this rare condition.

Difference in recurrence frequencies of non-muscle-invasive-bladder tumors depending on optimal usage of intravesical immunotherapy of bacillus Calmette-Guérin.

BACKGROUND/AIM: The therapy with intravesical instillation of bacillus Calmette-Guérin (BCG) after transurethral resection (ITJR) of the tumor is the gold standard of treatment of non-muscle invasive bladder cancer (NMIBC). The aim of this study was to compare the frequencies of reccurence between a group of patients submitted to TUR + BCG therapy (group I) and a group of patients submitted only to TUR (group II). METHODS: The patients with NMIBC, a total of 899, treated in our Institution from January 1, 2007 to March, 2013, were included in this study and divided into two groups: group I and group II. These two groups were divided into three subgroups: solitary first diagnosed tumor ≤ 3 cm (SFDGT), solitary first diagnosed tumor > 3 cm and multiple first diagnosed tumors (MFDGT), and recedive tumors (RCT). Statistical analysis was performed by using χ2-test and Kolmogorov-Smirnov test. RESULTS: In the group I a total of 133 cases had reccurence contrary to 75 in the group II, making a statistically highly significant difference. Analysis of recurrences through the subgroups revealed: in the group I SFDGT recurrence occured in 27 of the cases vs 9 cases in the group II; in the group I MFDGT recurrence occured in 49 of the cases vs 31 in the group II (p < 0.001), and finally, in the group I RCT recurrence occured in 57 cases vs 35 cases in the group II (p < 0.001). CONCLUSION: The obtained results indicate no difference in the frequency of reccurence between the group I and group II regarding SFDGT, but a very high significant difference regarding those with MFDGT and RCT. These results should be taken into consideration in everyday clinical practise.

Specificities of transplantation of kidneys procured from donors with situs inversus totalis--a case report and review of the literature.

INTRODUCTION: Situs inversus totalis (SIT) represents a total vertical transposition of the thoracic and abdominal organs which are arranged in a mirror image reversal of the normal positioning. We presented a successful pre-dialysis kidney transplantation from a living sibling donor with SIT and the longest donor follow-up period, along with analysis of the reviewed literature. CASE REPORT: The pair for pre-dialysis kidney transplantation included a 68-year-old mother and 34-year-old daughter at low immunological risk. Comorbid- ities evidenced in kidney donors with previously diagnosed SIT, included moderate arterial hypertension and borderline blood glucose level. Explantation of the left donor kidney and its placement into the right iliac fossa of the recipient were performed in the course of the surgical procedure. A month after nephrectomy, second degree renal failure was noticed in the donor. A 20-month follow-up of the donor's kidney and graft in the recipient proved that their functions were excellent. CONCLUSION: In donors with previously di- agnosed SIT the multidisciplinary approach, preoperative evaluation of the patient and detection of possible vascular anomalies are required to provide maximum safety for the donor.

Radical cystectomy in eldery.

BACKGROUND/AIM: Radical cystectomy is the method of choice for the treatment of muscle invasive bladder cancer. This major surgery is associated with many complications, especially in older patients. The aim of this study was to analyze preoperative comorbidity, and intraoperative and postoperative complicatons in patients older than 75 years. METHODS: This clinical, retrospective study included 46 patients over 75 years, who underwent radical cystectomy. Indications for surgery, and complications during and after the surgery were followed up. RESULTS: Preoperatively, anemia caused by hematuria was registered in 76% of the patients. In 52% of the patients urine derivation was performed by ileal conduit, in 35% by ureterocutaneostomy and in 13% orthotopic ileal neobladder was created. The average duration of surgery was 190 (120-300) min. A total of 76% of the patients were treated by blood supstitution intraoperatively, average 630 (310-1230) mL. Concerning pathological stage of transitional cell carcinoma of urinary bladder, 26% of the patients had T2, 4% T3a, 52% T3b, and 14% T4a stage. In one case, planocellular carcinoma was diagnosed by patohistological examination, and in 2 cases prostate carcinoma was incidentally found. The average duration of hospitalization was 16 (8-35) days. CONCLUSION: The main reason for cystectomy in patients over 70-and 80 years was gross hematuria caused by bladder cancer, with consecutive anemia which could not be solved using endoscopic treat- ment or blood supstitution. As expected, a prolonged stay in hospital after cystectomy, and a higher rate of complications were recorded in this population.

Uretrorenoscopy laser lithotripsy treatment of stones impacted in the left ureter 10 years after right kidney autotransplantation.

INTRODUCTION: Urinary tract calculosis is a very common condition in general population. It appears in 5-10% of population, and can be managed conservatively or by minimally invasive, endoscopic and surgical procedures or extra-corporeal shock way lithotripsy. Lesions of the ureter can be resolved by JJ stent insertion, end-to-end anastomosis, ureterocystoneostomy, percutaneous nephrostomy, nephrectomy, intestinal graft interposition or kidney autotransplantation. CASE REPORT: We presented surgical treatment and outcome in a female patient, with a large defect of the right ureter due to impacted stone treatment, following a successful autotransplantation of the right kidney. Ten years later a stone impacted in the left ureter was successfully treated by ureterorenoscopy and laser lithotripsy. Asynchronously combined kidney aoutotransplantation and ureterorenoscopic lithotripsy preserved kidney function. CONCLUSION: Bilateral organs preservation should be considered even in the absence of malignancy, especially in younger population.

Rare locations of metastastatic renal cell carcinoma: a presentation of three cases.

INTRODUCTION: Metastatic renal cell carcinoma (RCC) frequently spreads not only to neighboring lymph nodes, but also to distant organs, including the lungs, liver, bones and brain. CASE REPORT: We presented three cases of RCC with colon metastasis. In the first, 63-year-old patient, after left nephrectomy followed with lyphadenectomy in paraaortic lymph node, left hemicolectomy was done due to RCC metastasis in rectosigmoid colon. In the second, 35-year-old patient, left radical nephrectomy was followed two years later with partial right nephrectomy, lung metastasectomy, small bowel and coecum resection and right orchiectomy all as separate procedures in different time intervals. The patient died from brain and bone metastases two years after the first surgery. The third, 35-year-old patient, had right nephrectomy followed by repeted lymphadenectomies after 6, 12 and 24 months. Four years later RCC spreaded to coecum and right hemicolectomy was performed. CONCLUSION: RCC treated with nephrectomy should be carefully followed up with imaging methods as a proper treatment of RCC metastases to distant organs could be important for a patient survival.

[Post-voiding residual urine and capacity increase in orthotopic urinary diversion--standard vs. modified technique].

BACKGROUND/AIM: Ever since the time when the first orthotopic urinary diversion (pouch) was performed there has been a constant improvement and modification of surgical techniques. The aim has been to create a urinary reservoir similar to normal bladder, to decrease incidence of postoperative complications and provide an improved life quality. The aim of this study was to compare post-voiding residual urine (PVR) and capacity of the pouch constructed by standard or modified technique. METHODS: In this prospective and partially retrospective clinical study we included 79 patients. In the group of 41 patients (group ST) pouch was constructed using 50-70 cm of the ileum (standard technique). In the group of 38 patients (group MT) pouch was constructed using 25-35 cm of the ileum (modified technique). Postoperatively, PVR and pouch capacity were measured using ultrasound in a 3-, 6- and 12-month period. RESULTS: Postoperatively, an increase in PVR and pouch capacity was noticed in both groups. Twelve months postoperatively, PVR was significantly smaller in the group MT than in the group ST [23 (0-90) mL vs. 109 (0-570) mL, p < 0.001]. In the same period the pouch capacity was significantly smaller in the MT group than in the ST group [460 (290-710) mL vs. 892 (480-2 050) mL, p < 0.001]. CONCLUSION: Postoperatively, an increase in PVR and pouch capacity was noticed during a 12-month period. A year following the operation the pouch created from a shorter ileal segment reached capacity of the "normal" bladder with small PVR. The pouch created by standard technique developed an unnecessary large PVR and capacity.

Living unrelated donor kidney transplantation--a fourteen-year experience.

BACKGROUND: In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors. METHOD: We retrospectively identified 14 patients who received renal allograft from spousal donors between 1996 and 2009 (group I). The control group consisted of 14 patients who got graft from related donor retrieved from the database and matched than with respect to sex, age, kidney disease, immunological and viral pretransplant status, the initial method of the end stage renal disease treatment and ABO compatibility. In the follow-up period of 41 +/- 38 months we recorded immunosuppressive therapy, surgical complications, episodes of acute rejection, CMV infection and graft function, assessed by serum creatinine levels at the beginning and in the end of the follow-up period. All patients had pretransplant negative cross-match. In ABO incompatible patients pretransplant isoagglutinine titer was zero. RESULTS: The patients with a spousal donor had worse HLA matching. There were no significant differences between the groups in surgical, infective, immunological complications and graft function. Two patients from the group I returned to hemodialysis after 82 and 22 months due to serious comorbidities. CONCLUSION: In spite of the worse HLA matching, graft survival and function of renal grafts from spousal donors were as good as those retrieved from related donors.

Fournier's gangrene.

BACKGROUND: Fournier's gangrene (FG) represents a necrotizing infection of the skin and subcutaneous soft tissue of the external genitalia and perineum. It arises as a result of propagation of anorectal, urogenital and skin infections. The principles of treatment include improving general condition of a patient, debridement of wound, excision of necrotic tissue, combined antibiotic therapy, hyperbaric oxygen therapy and reconstructive procedures. It is a rare but very serious condition which regardless to aggressive treatment can lead to a lethal outcome in up to 20-30% of patients. CASE REPORT: Since the year 2000 we have treated six patients with FG. We presented the course and positive treatment outcome in a 65-year-old male patient with numerous comorbid conditions, nonregulated insulin-dependent diabetes, hypertension, previous myocardial infarction, chronic viral hepatitis and thrombocytopenia, rehabilitation was complicated with heart failure, atrial fibrillation and pulmonary thromboembolism. The treatment consisted of two extensive debridement of the wound with removing necrotic tissue, drainage, consolidation of state of health, correction of his blood sugar levels and thrombocytopenia, antimycotic and combination of three antibiotics and hyperbaric oxygen therapy. In two delayed surgical procedures reconstruction of a large defect of the urethra was performed. CONCLUSION: A patient with numerous and serious comorbid conditions with FG could recover as a result of teamwork of urologists, infective medicine specialists, cardiologists, endocrinologist, vascular and plastic surgeons.

[On 10-year experience in the use of direct and antireflux techniques of anastomosis of ureter and orthotopic intestinal neobladder after radical cystectomy].

BACKGROUND/AIM: Today, radical cystectomy is the method of choice in treatment of muscle invasive bladder carcinoma in stage T2-T4a, No-Nx, Mo, and orthotopic derivation is for patients the most comfortable derivation of urin. From 1888 when Tizzoni and Foggi performed the first orthotopic derivation on animals, and 1913 when Lemoin declared the first orthotopic derivation in humans there has been a constant improvement and modification of orthotopic urinary diversion after radical cystectomy which significantly decrease the number and severity of postoperative complications. The aim of this study was to compare complications regarding the direct and antireflux ureter-neobladder anastomosis. METHODS: This retrospective study included 79 selected patients operated over the last ten years having medical records available. Previously, we excluded the patients with prior radiation therapy, systemic illness, diabetes mellitus, previous history of calculosis and metabolic disorders etc. Hautmann orthotopic technique was used in almost 70% of the patients. We analyzed complications regarding direct and antireflux ureter-neobladder anastomosis with a median follow-up period of 4.72 years. We followed-up the appearance of unilateral and bilateral hydronephrosis, forming of renal stones in the patients without previous history of renal calculosis, and renal insuficiency caused by stenosis on the site of anastomosis. We used the Kolmogorov Smirnov test, Mann-Whitney U test, Student's ttest i chi2 test for statistic analysis. RESULTS: The median age of the patients was 68.2 years. Totally 88.61% of the patients were male and 11.39% were female. The direct anastomotic technique secundum Wallace was used in 43.03% of the operated patients and antireflux technique secundum Le Duc in 56.97%s. Renal deterioration caused by stenosis on the site of the ureter-neobladder anastomosis was statistically significantly higher in the antireflux anastomosis compared to direct anastomosis (chi2= 4.71, p = 0.0299). No one of the patients with direct anastomosis had poucho-ureteral reflux higher grade than gr III. CONCLUSION: In our study, complication as renal deterioration as a result of stenosis on the site of the ureter anastomosis was significantly more common in the group of patients exposed to antireflux technique.

[Extravesical diverticulectomy--a surgical technique for managing a giant bladder diverticulum].

BACKGROUND: Bladder diverticulum may be congenital and acquired. Iatrogenic bladder diverticulum is classified in a special group. Indications for surgery are: persistant or recurrent urinary infection, the presence of a stone in a diverticulum, development of tumor in a diverticulum cavity, the lower urinary tract symptoms and voiding symptoms and vesicoureteral reflux due to diverticulum or ureteral obstruction. CASE REPORT: We presented a patient with a giant bladder diverticulum. Transurethral bladder catheterisation was performed because of urine retention. Secondly, transurethral prostate resection solved subvesical obstruction. The third step was open, extravesical diverticulectomy. Post-operative course was without complications. Three months after the surgery, control intravenous urography revealed normal findings. CONCLUSION: We believe that the three-steps treatment of a giant bladder diverticulum significatntly contributed to the decreasing of postoperative complications.

[Supraselective embolization as a method for the management of renal vascular injuries].

BACKGROUND: Renal injuries are most often caused by traumatic injuries, but they can also be induced iatrogenically, during renal biopsy, percutaneous nephrostomy or lithotripsy. Vascular renal injuries may be treated by embolization, non-surgical or surgical methods. CASE REPORT: In this paper we presented a high-risk patient with poor outcome of an open surgery threatment and a prior attempt of embolization, with gross haematuria caused by traumatic renal arterio-venous (AV) fistula and pyelocalical injury who was managed by supraselective embolization of the irrigating arterial vessel. CONCLUSION: Supraselective embolization is a first choice method for the treatment of low grade renal vessel injuries. Even patients with the most severe renovascular lesions and major renal destruction (a grade IV injury) can be treated nonsurgically with supraselective embolization, with an excellent chance to preserve the maximal amount of functional renal parenchyma. This method is rapid, effective, tissue preserving, and likely to reduce morbidity and mortality.

[Uretero-transappendix-cystoneostomy as a technique for the reconstruction of the lower part of the ureter].

BACKGROUND: Any large missing part of the ureter may be replaced by transureteroureterostomy, psoas hitch, Boari flap, nephrectomy, renal autotransplanation or by the implementation of an intestinal graft. CASE REPORT: A patient with a defect of the lumbal-pelvic portion of the right ureter, after the managemenet of a penetrating and perforating gun shot wound was presented. The missing part of the ureter was seccessfully replaced with an appendix. The technique of uretero-transappendix-cystoneostomy complete with a Boari flap and a psoas hitch was used. CONCLUSION: By the use of an original combination of surgical techniques, a large defect of the ureter and the defect of the bladder, as well as the preservation of the renal function was achieved in a more successful manner.
